They do look very similar. Where did you get the set? How much?
I actually got the set at a Bevmo during the 07 Holidays. They had a set with the 10 year old offering but the manager allowed me to swap it with a Quinta Ruban bottle (The Port Wood ). Bottom line, the glasses were free because they charged me for the bottle. That was the only set I saw like that around, everyone else had sets with a rounded old fashioned type of tumbler.
Ardbeg sells a similiar glass here. The MJ glass might have a bit more Tulip shape on the lip like the Reidel SM Glass.
