Adrien Lastic 緩衝核心吸盤粗徑矽膠假陽具 7吋

The suction base actually holds on tile, which I didn't expect from something this girthy. I warmed it up first and the silicone got noticeably softer, way more comfortable than my old one that stayed stiff the whole time.

The dual density silicone is the real star here, squishy on the outside but with a firm core that holds its shape. The suction base sticks to my shower tile like it's glued there. Seven inches with this much girth is a lot to handle, but the flexibility makes it work.
