VërSpanken H2O is all about the pressure you like, it's about the temperature that feels right, and the texture that keeps you coming back for more. With the open-ended housing and snap closure, the user controls the pressure. Unlike other toys, the user can change the texture and even the temperature experience. There are three different insert options available in Smooth (Blue), Bumpy (Green) and Wavy (Purple) textures. With this variety the combinations are endless! The WaterWieners inserts can be used at varying temperatures by either warming them in hot water or chilling them in the refrigerator. Combine temperatures and textures while discovering a myriad of stroking techniques to change up the experience and keep him speechless! Try the upward curl, rocking and swiveling or maybe the twist and since VërSpanken is an open-ended toy and cleanup is a breeze! It's also great for couple play! Made of 100% recyclable materials, VërSpanken, like all Big Teaze Toys, contains no latex, phthalates, lead or heavy metals.
