Trinity Purple Vaginal and Anal Beads. Though they have a simple design and shape, the Purple Vaginal and Anal Beads give you effective and amazing internal stimulation. Inserting and removing is easy as both beads have a smooth exterior and are connected to each other by a sturdy nylon string. The secret to these beads comes after you insert them, as you will start to feel vibrations as you move around. These vibrations are caused by two additional balls located inside each of the purple beads. When you move, you will cause the balls to roll around, creating vibrations. When done, you can remove them by pulling on the nylon string loop located at the end. Material ABS plastic. Please note these Kegel balls come packed in a vacuum sealed without retail package
