Although the listing does say OEM profile.
I ordered a set, and I am not quite sure what "OEM" means in terms of Alps, unless perhaps it refers to whatever Matias is currently making.
My hope is simply that they are compatible with my 4 Alps keyboards: Northgate 101, AT101W, Filco Zero, and Ducky 1087XM in case I have to make substitutions.
And, of course, if I am one day so lucky as to get my hands on a Kingsaver .....
