Size: Approximately 27 x 24 cm, Gusset: Approximately 8 cm From the HP product description: A low-waste cotton bag made using "leftover fabric" from the bag manufacturing process. Born from a collaboration between Neal's Yard and "re-wrap," a UK-based women's support organization. The second edition is a mini size, perfect for lunch or a quick outing. It has an inner pocket and is highly functional. Made of thick, sturdy fabric, it can hold heavy items. I purchased this at the store a few months ago, but I haven't had a chance to use it, so I'm putting it up for sale. It's in very good condition. I will fold it and ship it via Nekopos (a Japanese delivery service).
