Give your arm a rest and allow the Autoblow to work a load or two out - automatically. The sleeve pops out in a second for easy cleaning. You'll need a water-based lubricant, plus you might want to use a toy cleaner to make sure your sleeve is squeaky clean after washing it. Unlike other masturbators, cleaning up after the fun is finished with the Autoblow, is simple. Made from soft, stretchy & pliable TPE. Length: 5.25", Depth: 3.25", Width: 2.5". Weight: 10 oz. Phthalate & latex free. Waterproof.
