My previous posting of three black spectacle cases (as new), didn't get any responses. So here is a 're-framing' which almost makes me want to keep them!
Possible uses for these? They just need to be imaginatively customised (stickers, collage, colour change) linked with a use change, such as pencil cases , gift boxes just right for delicious chocs or first aid kits for the car, kid's treasure box etc.
Google it and see what ideas are out there. e.g.https://craftingagreenworld.com/articles/ways-to-upcycle-eyeglass-cases/
