管端蓋 - 餅乾嵌件（已塗裝）

The paint job matches the rest of the set perfectly, and the insert clicks into the pipe opening with a satisfying snug fit that hides the raw edge completely. It's a small piece, but it makes the whole structure look intentional and polished.

It's nice to have a proper finished edge for the pipe openings instead of just a raw hole. The paint job matches the other pieces I have from this set perfectly, and it really completes the look of the build.

The little painted cap clicks right into the Biscuit System and instantly finishes off those raw pipe openings, which really sells the whole underground look. I was honestly surprised how clean the paint job is for such a tiny piece, and it stays put once pressed in.
