These waterproof finger vibes come in a variety of styles and colors, and come packaged with an extra set of batteries, making them a perfect item to stock near the cash register for impulse buys. The Ultra Finger Vibe (available in pink or blue) has a pet design with stimulating nubs, while the Double Finger Fun (one package contains pink and purple) are so tiny and discreet that they could be worn out in public for some spontaneous fun. The best, however, has to be the Mini Vibrating Egg (available in pink and purple), which is versatile. The egg has extended stimulating nubs and can be used by women for clitoral or vaginal stimulation, or it can serve as a cock ring for men. $
