Used zip-top plastic bags Height 26cm (24cm below the zipper), Width 17cm A5 size items fit perfectly. No gusset. 50 bags will be packed in one bag for shipping. These are not new. I collected these when I received medicine at pharmacies, and I now have a large number of them, so I'm selling them. They were only used to hold medicine, so they are not particularly dirty, but there may be some scratches. I try to select the cleanest ones, but they are not new, so please use them if you don't mind about hygiene and just want to sort things, etc. Thank you for your understanding.
