A snap-fit kit assembles entirely with pegs and sockets — no glue, no paint required to reach a finished, posable model. Modern Gunpla made the format famous: molded-in color, press-fit joints, and engineering tight enough that a first-timer gets a clean result with just nippers.
Snap-fit is why the hobby’s on-ramp is so gentle. Glue, paint, and airbrushing then become upgrades you add when you want more, not requirements to start.
