I don't know how old this shirt is.

Just posting these pictures on here hoping that someone knows how old this Korean table tennis shirt is.
Saw these on Depop for a good deal but I don't want to get an old shirt.

It’s very old. It even has the old BTY logo where the two wings are not symmetrical.
