Base - covers most layouts, including ISO-UK - (60%, 65%, 75%, TKL, 96-key, 1800/CP and fullsize)
Extension - extends coverage for other layouts (660, 88-key, 60% with arrows, Alice/split, standalone numpad), alternative legend keys, novelties, and includes extra keys so that you can have two modifier sets to dress up two keyboards (e.g. TKL/1800 + 60/65%) by reusing modifiers. You will not have enough for two full-size keyboards or two TKLs.
Hangul - further extend Dolch usage, now with Korean language sublegends – if you purchase ALL 3 kits, you may equip two keyboards fully with Dolch.
