This is one of the best masturbation sleeves for men we've found. It's made of an elastomer, and works best with a nice water-based lubricant (silicone-based lubricants will not harm it, but will soak in to the material right away). It's closed off at one end to provide some suction while thrusting, and its sensation nubs on the inside provide an interesting texture. 6 inches long.
The Blue Lagoon should be stored inside out (with the sensations nubs facing out).
Material: elastomer (silicone-free, latex-free and phthalate-free)
Batteries: none
Cleaning Instructions: Turn inside-out and clean with soapy warm water
Special Instructions: Water-based lube works best, as silicone-based lube soaks in quickly, and oil seems to degrade the material over time.
