Leopara uses nanosuction technology, which is a thin, non-adhesive material with thousands of suction domes ... think microscopic suction cups ... that quickly attach to any mirror with a simple press and form a vacuum seal. Because the nanosuction backing is not an adhesive, the sticky will not wear off. The holes may get trapped by dust and residue over time, so just a simple roll with a lint roller or wipe with a lightly damp cloth removes the residue and restores the suction. It's actually kind of magic.
