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. Since barrels and pickling containers take up space and get in the way when not in use, Lami-zip bags are very convenient. The size is 300mm (height) x 220mm (width). They are about the same size as A4 paper. In addition to these, I also sell Lami-zip bags of the same size with valves. Please purchase according to your needs.
