Doubleshot PBT Keycaps

PBT (short for "polybutylene terephthalate") is one of the hardest, most durable materials for keycaps. It is more resilient against heat and chemicals than ABS, but its properties also make it more difficult to mould, which makes it more uncommon and mostly found in high quality keyboards. PBT Keycaps are shine resistant and don’t absorb skin oils like ABS.
