Our MirrorPal Glass Labels effortlessly stick on the bathroom mirrors with the help of strong acrylic, tamper-proof adhesive. 3 mil thick metallic polyester label has a brushed metal surface (also called mirrored surface) and comes with a removable liner at the back. Once applied to the bathroom mirror, the label will not peel off. UV, water, oil, and chemical-resistant, the surface of the hand washing labels is easy to wipe clean.
