Crystalmark Dental High Quality Air Abrasion Resistant Mirror Head is a patented, innovative mirror head proven to maintain its reflective integrity through hundreds of air abrasion procedures. This mirror head will not fog or frost due to the indirect blast of an aluminum oxide particle stream (which would obliterate the surface of a conventional dental mirror in seconds)! The CrystalAir mirror head is constructed of gold plated stainless steel to help distinguish it from conventional dental mirrors. Mirror head is fully autoclavable. All mirror heads are backed by a limited lifetime warranty.
