It turned out the spacebar has 3 stems. Compatible with most ANSI keyboards. e.g. Filco, Rosewill, Ducky, Poker, Das, etc. It was supposed to be universal spacebar which has 6 stems, but they had some errors during producing the 6-stems spacebar, so the final product only includes a 3-stems spacebar for each keyset. And actually there're 105 keys included in each keyset. One extra stepped caps lock key for Cherry's keyboards.
Sorry about the mistake guys.
