I'm not 100% confident around 100% keyboards, but it seems to me like a standard 100%/full-size layout. You'd want to find keycaps that say that they are for 100% or full-size layouts. It looks like their website lists those as "Full Set Keycaps". If you have any other questions, lmk! I'd be happy to answer
Cool to hear your findings! I remember really wanting zilents way back before bobas existed, but not buying them because they're so expensive. Interesting to hear that you like the bobas more. Guess i'm not missing out on the zilents (anymore at least lol)
