Ensis 320 Luna is made from forged 1 mm aluminum alloy for a strong but lightweight construction. The hairline brushed surface maintains the full metallic luster of the alloy. With 1 mm natural rubber underside provides non-slip grip whilst still maintaining a very low overall profile of 2 mm. The Ensis 320 Luna was designed with in-house S.Q.A.T. technology that tests the data loss of the surface, many months of testing has been carried out to ensure that this aluminum mouse pad has an extremely low data loss whilst still maintaining ultra low friction glide.
