Dr. Dabber® Iso-Snaps are the perfect all-in-one solution to clean your rigs, nails, and glass. Each Iso-snap has cotton swabs with 70% isopropyl alcohol loaded in the shaft. With a snap of the top cotton swab the isopropyl alcohol is released from the shaft down into the bottom cotton swab head. Simply wipe the surface area clean to get a fresh surface. No need to use heat to clean after every use.
