I was going through some boxes of stuff I'd packed away about 10 years ago yesterday, and I discovered what I suspect to be fake Mesi highballs.
Fake some sort of Iittala anyway!
I've taken a pic of the highball next to what I think it a real Mesi shot glass. (Real Iittala even if not Mesi.).
The colour of the highball is completely wrong, it's green, compared to ice-clear; the rim is heat finished, but thick and lumpy compared to the real thing. The pattern is ultra simple, regular and repeated; the real thing is far more complex.
