I think there is some confusion here. None of KBDFans' Topre key sets is made by ePBT. I have never seen a single set of Topre keycaps made by ePBT, hence I asked.
I don't know of any ABS doubleshot Topre either, hence this offer is very interesting. The Topre stems in that one picture look very promising, they are thick and uniform unlike most aftermarket's PBT ones. The stem is key to why OG Topre sounds and types best. I hope the pictures represent the actual production keycaps.
