Hello, I am trying to find a supplier who can repair some storage boxes we have in our library. The boxes are made of strong cardboard and covered in burgundy cloth. They have a metal ring on the spine, open from the right and fasten with a plastic clasp. The boxes are similar to Niceday box files except the lid has a lip which overhangs the box. The area that needs repairing is the plastic clasp, which has snapped on a number of the boxes. If anyone knows a supplier that I could contact to enable me to get these boxes repaired, I'd be very grateful. Thank you, Melanie PS Our library is based in Leeds
