The Fleshjack Boys Colby Keller edition features a custom-molded sleeve made from Fleshjack's patented SuperSkin material. The interior texture is specially designed to mimic the sensations of real penetration and is based on Colby Keller's unique anatomy. The SuperSkin material is soft, flexible, and intended to feel like real skin, providing an immersive and pleasurable experience during use.

Like other Fleshlight and Fleshjack products, the Colby Keller Fleshjack comes with a discreet case that resembles a flashlight for easy and discreet storage. Regular cleaning and proper maintenance of the sleeve are essential for hygiene and prolonging the product's lifespan.
