DiscreetDuo ウェアラブルポンプ - ダイアフラム（1個のみ）

Finally got a replacement for my worn-out diaphragm and it snapped right into place with zero fuss. The pump is working like new again, which is exactly what I needed.

Worked perfectly straight out of the box, fitting snugly into my pump without any leaks. The silicone feels a bit stiffer than the original, but it still creates a good seal once you press it in firmly.
