This switches housing feature a mix polycarbonate plastic blend from TECSEE with some glitter accent. It is like a gem, "Bling Bling". Very smooth linear switches with 63.5g two stage, 22mm long springs. 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.
