This set is inspired by Tohsi Industrial Design’s “Eureka”, they used three different vintage keysets and blend them into an elegant mix-n-match keycap set on their keyBoard.When I first saw the caps, I found it so attractive and immediately reached out to them. They generously authorized me to make this interesting set from an idea to an actual product. Material: ABS material Production Method: DoubleshotProfile: Cherry profile  Design by Mars
