I wonder how many people actually buy GMK sets to use on a daily driver keyboard, and how many buy them as collector items. I bought the True Olivetti set from Originative a while back, but it looked too similar to a PBT "Siberian" keycap set I had bought on AliExpress. The Siberian set won out in the end since it's not going to get shiny, and I was afraid that the white GMK keys would yellow in the sun, but the GMK set was awfully nice looking.
