About KAT Operator Thickened Double Shot PBT Keycaps Ortholinear Set


The number and shape of keycaps to be incorporated into the kit were carefully selected to accommodate not only Corne V4, but also multiple keyboards from the previous Corne series and other orthogonal layouts, column staggered layouts, and so on.

In particular, we have incorporated 1u Blank keycaps and 1u/1.5u Convex keycaps, which are not available in the Base Kit, so that you can achieve a more personalized layout.

Also available this time is a coupon code that offers a substantial discount on the purchase price, thanks to our business partnership with Keyreative.
