The Autoblow Ultra is compatible with a range of interchangeable sleeves with different openings and various textures. This brown-colored sleeve with a mouth opening is made of realistic-feeling TPR. The stimulating structure on the inside provides a highly realistic blowjob simulation. The Ultra sleeves are easy to clean by running lukewarm water and a toy cleaner through the hole at the top. Let the sleeve dry thoroughly before placing it back into the housing.
