This is a great keycap set, especially at the sale price. Colors are nice and are a good match with the Shinai Green CSTM80 decorative case. The printing of each key looks good to my eye, and my wife is really excited to get them installed on her keyboard. Would recommend!
Really, there's not much to say with these. They're very solidly good enough, especially if you can catch them at the promo price of $39. The base kit has a ludicrous selection of keys, the plastic feels nice under my fingers and is plenty thick, the spacebars in my set seem visually straight and don't have trouble fitting on stabs, and the legends are pretty crisp and well-aligned.
Nothing's perfect, of course. There's some fading on the bottoms of the darker keys since they're reverse-dye-subbed rather than using colored plastic, and looking closely at keys with straight vertical legends (I, |, [] etc) I can see some misalignment. But, for the price, I'm happy, and expect to keep using these on any keyboard I have that matches their color well until I wear them out or damage them.
I ordered this set to match the base of my keyboard and the colours complimented eachother beautifully. I'm not sure what else to say because I just liked the colour and the novelty keys. It was on sale, so that was a bonus and the base kit came with a lot of keycaps. 10/10 would recommend to a friend ^^
