IKU Flex is built around texture. Stimulating ridges massage with every stroke, wrapped in silky-soft silicone for a lifelike feel — and like every IKU style, it clicks into a fully modular system you can build on.

 IKU Flex features an innovative, ridged interior designed to massage with stimulating texture on every stroke, while its silky-soft silicone surface delivers a genuinely lifelike, skin-to-skin sensation. At 1.8cm in diameter, it's a snugger fit than a standard sleeve, made from body-safe silicone and TPE for comfort and security. Like every IKU design, it uses FUN FACTORY's Magnetic Click System, meaning it clicks into a shared modular frame you can mix and match with other IKU styles to build a fully personalized setup. It's fully waterproof to an IPX7 rating for use anywhere the mood strikes, including the shower. The removable silicone sleeve rinses clean with warm water and soap, and the whole thing is backed by FUN FACTORY's 25-year warranty.
