ボールギャグ ブロック

The lock on this thing actually stays put, which surprised me after a cheaper one kept slipping loose mid-scene. The ball shape sits comfortably without any hard edges digging in, and the black finish looks as discreet as it reads in the listing.

Wasn't sure about the lock at first but it actually makes the whole thing feel way more solid. The ball shape sits comfortably and the black finish looks as discreet as I hoped.

The lock keeps it securely in place, which I appreciated during play. Only downside is the ball feels a bit firm after a while, but that's minor.
