Gripper Nipple Sucker Atomic Jock | 彈性TPR材質

These stay put way better than the rigid metal ones I used before, and the flexible TPR actually bends to fit instead of pinching in the wrong spot. Suction holds strong once you get them seated right.

Wasn't sure about the bendy material at first, but the suction is way stronger than I expected for something this soft. Wore them for about an hour and they stayed put the whole time.

Wasn't sure how these would feel at first but the suction is surprisingly strong and stays put once you get the placement right. The TPR has just enough give that they don't dig in, and cleanup is quick with warm water.
