Wipe off your glass pipe, vaporizer, and tools after cleaning, and maintain a tidy session space. These 5 premium cloths are largely sized at 21" by 21", allowing for heavy absorption and flexibility. Resin Rags are ideal for touching up or drying off your device. When used in conjunction with Higher Standards ISO Pure, they will wipe away residues from glass, metal, or silicone surfaces.
