Nice big rubber ball! Very nice compared to this brand's rigid/plastic breathable offering. However, the big downside is that straps simply don't support the ball. The ropey material is high friction and digs into the corners of the mouth - even with lipstick! When the ball is behind the teeth and particularly when tight it's even worse. Protect your sub's lips and mouth, get something with better straps!
Good idea, just wrong item.
She says her mouth is too small, but Im not sure about that. Will buy a smaller one next time thou, because its all about keeping her happy.
