Gunpla Tools for Beginners: Nippers, Sanding, and Panel Lining

You need one tool to build your first Gunpla: a pair of nippers made for plastic models. Bandai says so itself. Add a sanding sponge set and a fine panel-line marker once you’ve finished a kit or two, and leave the expensive single-blade nippers, enamel washes and spray coats for later.

Prices below are list prices at USA Gundam Store when we checked in October 2026, and the kits link to ToyNoble’s researched reviews.

Do you need any tools to build Gunpla?

Parts come attached to a frame called a runner or sprue; the small join is the gate.

Barely. Bandai’s What’s Gunpla page explains that snap-fit parts and multi-color molding mean no glue and no painting, and says a kit can be built with just one pair of nippers (our translation from Japanese). That page also says Bandai had shipped 700 million Gunpla by May 2020.

Some Bandai kits skip even the nippers. Entry Grade and some newer lines use “touch gates,” where parts twist off the runner by hand. Here is what the kits ToyNoble reviews list:

On a High Grade or anything bigger, you’ll want nippers. Twisting parts off a standard runner leaves torn plastic and white marks.

Bottom line: Buy nippers before your first HG. Everything else on this page is optional.

Which nippers should a beginner buy?

Bandai’s notes on handling tools and paints tell builders to use nippers made for plastic models or single-blade nippers, not general-purpose cutters. Plastic-model nippers have thinner tips that fit into narrow gaps and cut parts cleanly without crushing them, the page says (our translation).

These are the nippers USA Gundam Store listed on Oct 7, 2026:

Double-blade nippers squeeze from both sides and tolerate thicker gates and a little twisting. Single-blade nippers cut with one thin edge against a flat anvil, which leaves a cleaner cut but chips if you use them on thick plastic. The USAGS listing says its single-blade nipper is “designed to cut thin plastic,” recommends protective glasses because small plastic may chip off, and asks you to cap the blade after use.

Our take for a first nipper: a $11 to $17 pair. You’ll learn the two-step cut on it, and if you later buy a single-blade nipper, the cheap pair becomes your first-cut tool so the expensive one only does the final trim.

How do you cut parts without white stress marks?

Even touch-gate kits like Entry Grade Kirby leave a small nub where each part met the runner.

White marks appear when plastic bends or tears near the gate. The fix is a two-step cut, which builders recommend in a Reddit thread from a first-time Frame Arms Girl builder: cut the gate a few millimeters away from the part to free it, then trim the leftover stub close to the surface.

1. First cut: Cut the runner side of the gate, leaving a stub on the part. Don’t twist.
2. Second cut: Lay the flat side of the nipper against the part and trim the stub.
3. Clean-up: Sand or shave any small nub that remains.

A hobby knife helps with step 3, but go slowly. Bandai’s tool page recommends a replaceable-blade art or design knife over a snap-off utility blade, which can break under pressure, and asks that young children use knives with a parent. Tamiya’s modeling guide adds a simple rule: “Remember to change blades as they become dull.”

Budget knives at USA Gundam Store started at $7.99 for the USAGS Modelers Knife when we checked. If you’re buying for a child, skip the knife and use sanding sponges instead.

What sanding tools do you need, and what grits?

Sanding removes the nub left after cutting. Bandai’s tool page says higher-numbered sandpaper is finer and gives a cleaner finish, and suggests keeping a few sheets of waterproof sandpaper between #400 and #1000 (our translation). Tamiya’s guide says its abrasives run from coarse #100 to fine #2,000 and #3,000.

A sensible order: start at #400 for the nub, move to #600 or #800, and finish at #1000 or finer so the spot doesn’t look scuffed. On unpainted, colored plastic, coarse grits leave visible white haze, which is why the finer sets matter more than they seem to.

One warning from the Frame Arms Girl thread: don’t over-sand joints. A commenter said 5 to 10 seconds with 800-grit is enough on a tight joint, because sanding too much leaves a limb that won’t hold a pose under a weapon’s weight.

How do you panel line a kit as a beginner?

Small kits like the SD EX-Standard Wing Gundam Zero show panel lines clearly once they’re darkened.

Panel lining means darkening the engraved lines on armor so details read from across the room. Beginners have two choices: a marker or a liquid wash.

Markers are the easier start. Bandai’s Gundam Marker sets include fine-tip pens for this job. The GMS124 Gundam Advanced Marker Set ($22.99) has five chisel-tip markers and one fine tip for panel lines, and the GM310 Gundam Marker Erasure Pen ($3.99) cleans up mistakes.

Washes flow into lines on their own. The Tamiya Panel Line Accent Color page says each 40cc bottle contains enamel paint with a brush in the cap, and says to “Use on Tamiya Color lacquer or acrylic paints.” The brown version was $7.99 at USA Gundam Store; the black was out of stock.

Here’s the catch most beginner lists skip. Bandai’s tool page warns that enamel paints can damage parts, and that enamel, lacquer and alcohol-based solvents can damage ABS plastic. It also says alcohol-based Gundam Markers shouldn’t be used on parts from runners marked “ABS” (our translation). Check the letters molded on each runner before you line a joint part, and keep washes off stressed joints and pegs.

Bottom line: Use a fine marker on your first kits, check runner labels for ABS, and try washes on a spare part before a finished build.

What about top coats, decals and glue?

None of these are needed for a snap-fit kit. They’re the next step once you enjoy the hobby.

• Top coat: A clear spray that hides sanding marks and evens out the shine. Bandai’s tool page singles out water-based “Top Coat” as the exception in its spray warning; for other spray paints, it says to check the paint type because some can’t be used on ABS. Mr. Hobby’s B523 Mr Super Clear UV Cut Matt was $12.75 at USA Gundam Store, and its listing calls it a solvent-type coating.
• Decals: RG and MG kits often include waterslide or “realistic” decals; tweezers help. USAGS straight tweezers were $6.99.
• Glue: Snap-fit Gunpla doesn’t need it. Tamiya Extra Thin Cement ($5.99) is for glue-together kits and repairs.

Spray coats, lacquers and enamels release solvent fumes. The EPA’s page on volatile organic compounds indoors lists paints and hobby supplies among VOC sources and advises: “Make sure you provide plenty of fresh air when using these products.” Bandai’s page also says to use spray cans somewhere well ventilated and let Gundam Markers dry fully.

What does a starter tool kit cost?

Three budgets, built from USA Gundam Store’s listed prices on Oct 7, 2026:

Bandai also sells a Model Kit Entry Tool Set at $21.99 with nippers, tweezers and a parts separator. It’s a tidy gift, though you’ll still want sanding sponges.

Prices and stock change often. A few items in this guide, like the GodHand SPN-120, were out of stock when we checked.

Which kits make good practice pieces?

HGCE Rising Freedom Gundam, $27.99: a good second or third kit once you have nippers.

Our guide to Gundam kit grades explains how EG, HG, RG and MG differ in parts and difficulty.

How should you set up a workspace?

A small, flat, well-lit space beats a fancy desk. What helps:

• A cutting mat or tray so parts don’t roll away. In an r/Gunpla thread about a 5-year-old’s first EG kit, a parent of a son about to turn 6 said they were getting nippers, a small hobby mat and sanding sticks before picking more kits.
• A small dish per runner letter to sort cut parts.
• A desk lamp so you can see nubs and stress marks.
• Ventilation if you use markers, washes or sprays.

For children, follow the age on the box and stay close. Bandai’s tool page asks that young children use knives and files with a parent. Replies in that same thread suggested 30 Minutes Missions kits for young builders and warned that sticker-heavy kits can frustrate them.

Which tool setup fits you?

A child aged 8 to 10 building a first kit

Pick a touch-gate kit and skip tools at first. If they move to HG, buy a $11 to $12 double-blade nipper and a sponge set, and keep knives with an adult.

A teen or adult trying one kit

A $20 kit: Bandai Entry Nipper plus the God Sponge File A set. That covers an HG with clean results.

Someone who already finished two or three HGs

Add a $17 to $35 single-blade nipper for final cuts, the finer sponge set, and a fine panel-line marker.

A builder who wants a show-quality finish

Add a top coat, decals and tweezers, and learn washes on spare parts first. Read the runner labels for ABS before any enamel or alcohol-based product.

A gift for a new builder

Bandai’s $21.99 Model Kit Entry Tool Set plus a $12.99 to $20.99 kit makes a complete first box.

We keep our model kit reviews up to date with prices and box ages as new kits arrive.
