The Liquid Chrome practice hand is the latest in technology for practicing nail techs as well as seasoned professionals. This hand is made of high quality silicone and is acetone resistant. These hands are wired for pose-able movement and realistic photos. The hand can be washed with mild soap and water. *take care to not over extend the wire, as it may break. Hands may have individual flaws and can be injured the same as skin. Please take care while using a file. If there’s product on the hand that sticks to the silicone, the hand can soak in acetone.
