Hello, Jock: I believe that all of us are unsure about what you are trying to communicate. Are you trying to BUY buckles or are you trying to SELL buckles for you/from you? Are they: all leather, leather covered, or what?
In my part of the US, for instance, belt buckles (of any sort) are VERY DIFFICULT to sell, because most people will buy a belt with the buckle permanently attached (in other parts of the US, results may be different- I don't know...). In the '70s, buckles were very popular & people would change buckles depending on their moods- the '70s are long, long past, however, around my neck of the woods.
[if you are interested in buying leather covered buckles with exotic leather inserts, btw , I have many, many for sale- CHEAPLY- &, I'm sure, others on this forum do also.]
Anyway, please clarify. Thanks.
