They are not necessarily SA profile, since that is a name that Signature Plastics gives to its tall spherical keycaps made by them. We don't know who made these, so you can't really call them SA. They are definitely tall sphericals, though.
I saw the thread about these earlier today on Deskthority. I was going to post it here, but I got busy.
What I want to know is how can I order some? I have a tenso.com account, but I dont read Japanese. And Chrome wasn't very helpful with translating the pages at Diatec. Any advice?
