Someone else might have a good idea of local places to get mesh in Sweden,but I'd think you should be able to find something from Amazon.If you absolutely have no other options and must go with one of the 50 or 100 meter rolls,a 50 meter roll could probably be used with more bins than most people would ever want or need!Though it could be used for extra projects as well,like making a rabbit run style playpen for hamsters(roofed run with wood and wire)or also be used for travel cages,carriers,or hamster(or even other pet)-proofing things like wire rabbit cages with larger bar spacing and general things like that.I think you'd have mesh for decades after though,so it is kind of annoying
