Crafted from CyberGlass, one of the most highly sought after materials on the toy market today, the Adam & Eve Bree Olson CyberGlass Sweet Swirl Mini Vibe or the Polka Dot Micro Mini provides an excellent alternative to plain, run-of-the-mill 3" x .5" bullet vibes. Each multi-speed love bullet is encased in a non-removable, clear glass sheath decorated with either dots or swirls in soft pink and is accompanied by a velveteen storage bag. Though not made of solid glass, these mini's retain great glass selling features: they translate temperature and are phthalate free.
