So, the Slender Beads are great. You'll love them! Butt, they're from an anal-geared line called the Eclipse and we can't help butt wonder if the manufacturers were waiting to see who'd be the first to come up with a moon joke. We won't do it! We will say though that these silky, extra flexible and multi vibrations might eclipse some of the other butt toys in your collection.Aside from a classic beaded shape and twelve super powered vibration modes, the Slender Beads feature dramatic flexibility. The entire strand can be bent, twisted and curved into just about any shape. Perfect! A nice big base also acts as a barrier against too-deep penetration, so playtime will be worry and slip-free.Vibration is controlled with a simple push button at the base. USB rechargeable, the Slender powers up via an included USB charge cord. 60 minutes of charge time will thrill for up to 70 minutes.In hypoallergenic silicone, the Slender Beads sanitize easily and thoroughly for good clean fun. Wash well before and after use using warm soapy water or a favorite toy care fluid/foam. You will, of course, be using lots of lube with this toy, so be sure to choose a good quality water-based formula. Please don't be tempted to use a silicone lube- it could break down the material. On that note, it's best to keep this (and any silicone toy) away from other silicone products. Waterproof.
