交換用 フィラーキャップ アセンブリ (300301用)

Fits the 300301 perfectly and the assembly feels solid once snapped in place. The colour is a touch off from the original, but that’s expected with the paint process, and it’s barely noticeable unless you look closely.

The colour matched my unit closely enough that you'd have to look hard to spot the difference, which is exactly what I was hoping for given the paint process note. Snapped on without any fuss and feels solid.

It fit perfectly onto my unit without any fiddling, and the color match was close enough that you’d have to look hard to spot the difference. The assembly feels sturdy and clicks shut just like the original.
