glasses - frames

It's not your imagination, though many small repairs are often done for free. Lord knows they make enough already by selling frames bought at 5 Euro for 150 Euro.

I've no idea about Bxl but I had a similar break and my local Hans Anders repaired them free of charge. They had not been bought there - though my newest pair have been!

If there is no break and just needs a screw, it will cost little or possibly nothing.
