Hello, I don't know anything about keyboards (yet)... Can somebody help me?

[Ciderus]

I started looking into IMSTO's japanese key caps because... they look cool, but when I saw them in other pictures than the one I saw first, they didn't have the same color. This is the kind of color i'm looking for, some very warm beige, almost like white chocolate. I also want to buy key caps that have most of the universal keys (i.e a-z and modifiers) be from the japanese layout, and the region-specific ones (1-9 and all the symbols) be nordic/swedish. So far I've just thought I should buy one of each and mix-match, but that hinges on the fact that both layouts have the same color for the legends, something imsto doesn't appear to do...

Anybody know what I should do/have any suggestions/tips?

The one you linked is what I believe a sort of Realforce Hi-Pro with JIS layout, they're high profile sculpted keycaps

However Realforce use topre switch which have different mounting system than Cherry MX and similar stuff (Gateron, Kailh, etc)
They're what they are, can't be compared in terms of feel, each of them is unique and are based on personal preference

Well firstly we need to know what keyboard you currently have or planning to own,
and from there we can see what option you have

keycaps also have various options, in terms of their profile, sculpt, materials, legends, color
it can be quite confusing/complicated but it's fun

something like IMSTO they offer mostly PBT based set, with cherry profile
