These are the good rubber domes, right?

Do you happen to know if they're single-membrane or dome-per-key?

These are brand new and have never been used.
Can you see through the (never even opened) wrapping plastic around the KB what sort of dome?
What it is supposed to look like?

I have not been able to find out how a key is built-up on these keyboards.
Without taking the keyboard apart, there is no way to ascertain what's inside, sorry.
These are NOT clicky keyboards like the ole M type.

It turned out that I have an identical (except mine is charcoal) KB out in the garage. So I popped a key off and looked. It looks like each key has a post on the underside which fits inside a bigger post of the keyboard itself. Down inside of the KB post is the rubber dome and it doesn't appear to be individual domes like the little blue ones on some of the notebook keyboards, but rather a sheet with individual domes underneath where each key sits. Of course I can't really tell unless I took the keyboard apart.

Excellent! Thanks for confirming. My curiosity is now satisfied.
