The Pi Vibrator features an arch of beads. If you love Tantus' Ripple Small you'll adore Pi. Not only does it have the small sensible appeal but it's curved for the body and it vibrates. All the elements feature a new ergonomic base with a grooved base that holds the thumb and is angled for a uniquely comfortable experience. The Pi is a perfect toy for solo or couples play. It also features a removable vibrator that can be easily replaced or upgraded to a multi-speed unit.
