I bought these for Jon a few months back and have not been able to ID them.
Each glass has fish moulded all the way round the main body, the bases are smooth and concave.
Somebody unfortunitly has been at them with what looks like wire wool as they are really scratched inside.
The are a really good sized tumbler shape, they weigh 430g each, 8.5cm in diameter, 10.5cm in height.
I have no idea on the maker or country of these
many thanks in advance
