Made by Signature Plastics, these keycaps come in the Signature Plastics Low Profile, a similar construction to the Cherry Profile. Instead of using cheaper and less durable ABS, they used PBT plastic, giving you a more textured feel as well as better resistance to heat, shine, and solvents. As the 78-key set comes with many non-standard sized keys, it’s a useful kit if you’re building your own board.
