It seems like Skyloong liked their Silent Glacier series pretty well too, bringing two new switches to the series of silent switches from Haimu. Copper is a somewhat unique switch name, I can't think of another off the top of my head, and I love the blue.  Also, I'm shamelessly part of Skyloong's referral program if anyone wants to buy these directly from them https://skyloong.vip/?ref=rva4lyiv  Actuation Force: 48g Actuation: 2.0mm Bottom Out: 3.8mm
