The Fleshlight (also markete as the Fleshjack) is a sex toy designed and marketed by Interactive Life Forms (ILF). The Fleshlight is named for the flesh-like material used in its inner sleeve, as well as the plastic case that houses the sleeve, which is fashioned to look like an oversized flashlight. The inner sleeve is available with vulva, anus, mouth and a more discreet slot-shaped orifice. All of which also come in a choice of various colors and internal textures - one of the newest textures is called the STU (stamina training unit).
