I will sell 10 pieces of the item in the photo, divided into smaller portions. These are normal, without valves. I mainly use them for making miso, pickled plums, and fermented seasonings. Lami-zip bags are convenient because they don't take up much space when you're not using the barrels or pickling containers. The size is 300mm (height) x 220mm (width). It's about the same size as A4 paper. In addition to this, I also sell Lami-zip bags of the same size with valves. Please purchase according to your needs.
