These are made incredibly well, with perfectly stitched thick fabric case and a strong metal zip that glides smoothly, no getting stuck with this zip. I was lucky to get my hands on these while the supplier was getting rid of them for new stock, so I'm passing the saving onto you guys. These were $10 each in the shops.
Size: 25cm from tag to tag, 22 cm of inner case space and 6cm x 6cm around the midsection. It's an average size pencil case.
