Cooler Master MasterKeys PBT keyboards are made not to shine
 

Mechanical gaming keyboards are wonderful, but the make and model of the key switches are only part of a luxurious typing experience. Cooler Master's new MasterKeys S PBT and MasterKeys L PBT keyboards come with keycaps made from polybutylene terepthalate (PBT) plastic rather than the usual acrylonitrile butadiene styrene (ABS), perched atop Cherry MX switches in Blue, Brown, Green, Red, and Silver varieties. As gerbils may have already guessed, the MasterKeys S PBT has a tenkeyless layout, while the MasterKeys L is a full-sized affair.
