There are plenty of unique features to enjoy about this Pari Dual Ended Wavy Silicone and Glass Vibrator! Plush, silicone vibrators are some of the sexiest on the market, but glass dildos are a favorite for penetration. Combine both glass and silicone for the best of both worlds! The materials alone aren't the sexiest thing about this unique toy, however. The silky smooth, premium silicone makes up one side of the vibe while the strong and smooth glass makes up the other end. The wavy ends are slightly different and allow you to penetrate yourself and massage every angle of your soft, wet, insides! Use the angle to apply more pressure with less work. Get at your G-spot and even your back wall with plush silicone or smooth glass! Enjoy feeling the buzzing vibration through the core of both with 3 speeds and 7 patterns of vibration to enjoy! Notice the subtle differences between silicone and glass as the vibration comes through both ends in different ways. Made out of borosilicate glass, this end is non-porous, durable and super smooth. The plush silicone end is phthalate-free and body-safe when used with water-based lubricants. To recharge, plug in the USB cable included. Rated as IPX6 waterproof, you can expose this to strong water jets in a shower but it should not be submerged under water. Wash with warm water and mild soap after each use and then rinse and spray with a toy cleaner before wiping dry and storing in a cool, dark place. Slip some lube on the tips of this toy and then use the rest on yourself. As you slip the glass end in, enjoy how smoothly the glass glides against your skin. Rub it over your little pearl and massage yourself to an aroused state. Switch sides and notice the slightly more grippy feel of the plush silicone as it both massages and penetrates you! Use this slender vibe alone or with a lover. Built small and compact, it's perfect as a travel toy, too!
