So the question is.. are you going to use them? They're just so pretty untouched haha. Now I might be wrong but, didn't you already have a Russian set? If you did, what makes these more special? If not, I must be thinking of somebody else >.>
A few weeks ago I did receive two other sets of dyesubs like this. I got a used G81-3000SAV (heavily yellowed keyboard, reasonable condition caps) and a new set of ESA-3000-HASRO keycaps with no keyboard.
Those two were nice to get, but there were two things that made me less excited for them :
The G81-3000SAV was missing its extra Ukrainian keys, which these two 3100s both have. The ESA-3000-HASRO was missing its keyboard, which is quite important to me.
If I'm going to use any it'll probably be the 3000SAV keycaps, since they're already used.
Interestingly (to me anyway), there are some small differences between the keycaps of the HASRO, 3000SAV and 3100SAV (there are actually differences between the two 3100SAVs, as they're made 1 year apart). When I return home I'll make a thread comparing all four keysets in full!
