Bandai Spirits Hobby Tools - Parts Separator for Plastic Models Review (2026)

What the tool solves

Snap fit plastic model kits, Gunpla especially, rely on tight friction joints that hold parts together without glue, and those same tight joints make correcting a mistake or swapping a part frustrating without the right tool. Prying a snap fit joint apart with a flathead screwdriver or a hobby knife risks gouging the plastic or leaving visible scratches on a finished surface, which is exactly the problem Bandai built this separator to avoid. Because it is resin rather than metal, the tool is soft enough not to mar plastic the way a harder pry tool can, while still being rigid enough to apply real separating force.

How the separator works

The tool works by inserting a pin end into the seam of a joint and using it as a lever to push the parts apart, rather than prying from the outside edge the way a flat tool would. This pin and push method targets the gap in the joint directly, spreading force where the plastic is designed to flex rather than across a visible surface. A dedicated notch is also built in for poly cap joints specifically, sized so that inserting the tool into the poly cap before pinching keeps the cap from getting crushed or misshapen during disassembly, which is a common risk with other improvised tools.

Build and ergonomics

Bandai shapes the separator to sit comfortably in the hand, aiming to make it approachable even for beginners who are disassembling a kit for the first time to fix an assembly order mistake or swap a part between builds. The resin material is durable enough to be reused across many kits without wearing down or breaking under normal use, which matters since this is a tool meant to live in a builder's kit for the long term rather than get replaced often. Its official Bandai branding also means it is shaped and sized specifically around the tolerances of Bandai's own snap fit joints.

Where it fits in a build

This tool earns its place mainly during troubleshooting rather than as a step in every build, useful for correcting parts assembled in the wrong order, swapping color variants between kits, or carefully taking apart a completed model to repaint or upgrade a joint. Builders working mostly with glued plastic kits rather than snap fit Gunpla will get less regular use out of it, since traditional glued kits are not designed to be pulled apart and reassembled the way snap fit joints are. For anyone building Gunpla regularly, though, having a dedicated separator on hand removes the temptation to reach for a knife when something needs correcting.

Value as a single purpose tool

At a low price for a single dedicated tool, the separator is an easy addition to a Gunpla toolkit rather than a major investment, and its narrow purpose is really its strength since it does one job, prying apart snap joints safely, better than a multi tool or improvised pry bar would. It is not a multi size set with different blade widths for different joint gaps, so builders working on a wide range of kit scales may occasionally find a joint too tight or too loose for the single profile to handle ideally, though this is a minor limitation for most Gunpla work.
