Made from PBT plastic-long considered the superior keycap material-this MX-compatible set is both long lasting and resistant to the shine that occurs after long hours of typing. Compared to ABS material, PBT is less common and feel textures and more more durable. It’s dry and not easy to get oily. It won’t wear down over time like ABS does. Retro Mario Red and White PBT keycaps set has a full size base set and some extra novelty keycaps. Especially, the custom pattern for function keys is easy to use. No matter you got a 60%/75%/80%, TKL or a full size keyboard, we cover it all. This set will fit any size keyboard. Get one set and make it all work. Well-packed keycaps set with the custom storage box can be an ideal gift for anyone who’s into colors.
