I don't know how I hadn't found this till now but I'm a fan though I defo have some queries.
1: Any chance of an accent Esc key in the addition kit? As it is there are no R2 Novelties so its kind of disappointing knowing I wouldn't be able to have any variation on the Esc key, this is also something I'd like to see with alot of the other keys in the addition kit but its understandable not wanting to make it too big due to pricing.
2: I agree with some other users that the arrow keys seem a better fit for the Sakura kit moreso than the Novelties kit or even the base kit because especially as a 40's user, its a pain to have to buy an entire kit when all I really want from it is the arrow keys while half the others don't even fit onto boards.
3: I also agree with users pointing out the lack of a Fuji Novelty but equally the other novelties seem kind of lackluster in the amount of designs, with only identical novelties available for R3 and R4 (not including arrow keys) with no change in novelty design or colour, and currently no novelties for R2 other than part of an ISO space, I feel like some extra variety here would make it far more appealing.
Looking forward to seeing this set rip my wallet apart because damn those colours are nice.
