Snap-fit kit

A snap-fit kit is engineered so its parts click together securely without needing plastic cement, using precisely molded pegs and sockets rather than plain flat joints that would fall apart without adhesive. Many Gundam and other character model kits are built this way, which lets a beginner build a complete, poseable model straight from the box with no gluing step at all, and no cure time to wait through between stages.

Snap-fit does not mean glue is never useful on these kits. Builders who want a stronger long-term hold, or who plan to disassemble and repaint parts individually before final assembly, often still apply a small amount of cement or CA glue at key joints, particularly on kits that will be handled or posed often, since repeated snapping and unsnapping can loosen tight-tolerance joints over time.

A common mistake is forcing a peg into a socket at the wrong angle, which can snap a small connector point that was never designed to flex sideways. Test fitting parts gently before pushing them fully home, and consulting the instructions for the correct order and angle of assembly, prevents most of the small breakages that come from rushing a kit that otherwise needs no tools at all.
