Ultimate guide to collecting Gunpla model kits in 2026

Starting a Gunpla collection is more than just buying a few boxes of plastic. It is an entry into a global community of builders, artists, and engineering enthusiasts that has been growing for over four decades.

Gunpla, a portmanteau of “Gundam Plastic Model,” refers to the massive world of poseable mecha kits produced by Bandai Spirits . Celebrating its 45th anniversary in 2025, the hobby has evolved from simple toys into intricate works of art that combine engineering with creativity. Whether you’re a first-time builder or a seasoned collector, this guide covers the essentials of the Gunpla hobby, from choosing your first kit to finding rare Japanese exclusives.

What is Gunpla?

At its core, Gunpla is the hobby of building scale models of mobile suits from the “Mobile Suit Gundam” anime franchise. Unlike traditional model kits that require glue and paint, modern Gunpla kits are designed to be “snap-fit.” This means the parts click together with precision, allowing you to build a highly detailed, articulated robot without the mess of adhesives.

The hobby is more than just assembly. For many, it’s a creative outlet that includes detailing, painting, and weathering to make a plastic kit look like a real, battle-worn machine. It’s also a meditative experience. There’s a specific satisfaction in the “click” of two parts coming together perfectly. Since 1980, Bandai has refined its manufacturing techniques to create some of the most advanced plastic models in the world. Today, the kits range from palm-sized versions to massive, two-foot-tall engineering marvels.

Gunpla grades and scales explained

Understanding the hierarchy of “grades” is the first step for any collector. Each grade represents a different scale and level of complexity. If you’re just starting, the variety can be overwhelming. But here’s the short version: the grade tells you how big the kit is and how many parts you’ll need to manage.

Entry Grade (EG) and SD Gundam

Entry Grade (EG) kits are 1/144 scale and are perfect for newcomers with parts that snap off by hand, requiring no tools or nippers. They offer a surprisingly high level of articulation and color separation for their price.

Super Deformed (SD) are non-scale kits with “chibi” proportions, offering a fun and fast building experience. These are great for desk displays or for younger builders who want to see results quickly.

High Grade (HG) and Real Grade (RG)

High Grade (HG) is the most popular 1/144 line with the widest variety of mobile suits from every Gundam series. If there’s a specific suit you love from an anime, there’s a high probability an HG version exists. They are the “standard” of the hobby. For a great selection, check out our range of Gundam HG kits.

Real Grade (RG) is also 1/144 scale but features extreme mechanical detail and an inner frame for realistic movement. Think of these as Master Grades shrunk down to a smaller size. They are more challenging but look incredible when finished. You can find many Gundam RG kits that push the boundaries of what’s possible at this scale.

Master Grade (MG) and Perfect Grade (PG)

Master Grade (MG) kits are 1/100 scale, making them larger and more presence-heavy on a shelf. They feature sophisticated mechanical gimmicks and full internal skeletons. For many collectors, our Gundam MG collection represents the sweet spot between detail and size.

Perfect Grade (PG) is 1/60 scale, representing the absolute pinnacle of Bandai’s engineering. These kits often include LEDs, thousands of parts, and metal components. They are expensive and time-consuming but serve as the centerpiece of any collection.

Essential tools for your first build

While you can start some kits like Entry Grade without tools, a basic toolkit will significantly improve your results. Even High Grade kits benefit from proper equipment.

• Side cutters (Nippers): These are essential for cleanly removing parts from the “runners”. Avoid using standard wire cutters, as they can pinch and stress the plastic, leaving white marks.
• Hobby knife: This is used to trim away the small plastic “nubs” left behind by the nippers. A sharp blade allows for precision work that nippers can’t quite reach.
• Sanding sticks: These are for polishing nub marks until they are invisible. Start with a lower grit and move to a higher grit for a smooth finish.
• Panel line markers: These fine-point markers are used to emphasize the grooves in the plastic, making the model look more three-dimensional. It’s the easiest way to make a kit look “pro” without painting.

We carry a variety of tools from top brands like TAMIYA to help you get started on the right foot.

How to source authentic and rare kits from Japan

For serious collectors, the hunt for “P-Bandai” (Premium Bandai) and event-exclusive kits is part of the fun. These limited editions are often only available in Japan or through specialized retailers.

The P-Bandai factor is a major part of the secondary market. These are limited-run kits featuring unique colors or expansion parts not found in standard retail versions. Because they aren’t sold in typical hobby shops, finding a reliable source is key.

Authenticity matters when you’re investing in rare collectibles. Sourcing directly from Japan ensures you get “Japan-made products” that meet the highest quality standards. This avoids the risk of bootlegs that often have poor plastic quality and loose joints.

Discovery Japan Mall is a prime destination for international collectors looking for rare, unique, and popular Japanese items. We offer a direct bridge to BANDAI SPIRITS products, including limited edition Gunpla. If you’re looking for the latest new arrivals or hard-to-find exclusives, our platform makes it easy to browse thousands of items. We also offer a proxy purchase service for items that might be difficult to find elsewhere.

Pro tips for displaying and maintaining your collection

A growing collection needs proper care to keep the plastic and decals in top condition. Don’t let your hard work go to waste by leaving kits in a pile on a shelf.

• Action bases: Use dedicated display stands to pose your models in dynamic aerial positions. Most kits have a standard mounting hole that fits these bases perfectly.
• Dust management: Dust is the enemy of any display. Keep your kits in glass display cases if possible. If not, use soft makeup brushes for regular dusting to avoid snapping delicate antennas or parts.
• Top coating: Applying a matte or gloss clear coat protects the plastic and helps decals stay in place over time. It also removes the “plasticky” sheen from the model, giving it a more realistic appearance.
