This switches housing feature a mix polycarbonate plastic blend from TECSEE with some glitter accent. It is like a gem, "Bling Bling". The switches also utilize a UHMWPE stem for a more solid bottom out sound with very lightly lubed and while they are ready to go on any mechanical keyboard, those inclined to tune their switches will find an excellent starting point. TECSEE Sapphires are an excellent middle ground between mid-strength and high tactility switches featuring a nearly start of downstroke, yet well dispersed tactile bump aided by a 63.5g progressive spring design.
