I've been using this to store things like plastic bags, and I haven't carried any items, including food, in it, so it's in good condition. It has been washed with oxygen bleach, so it's clean and sanitary. I don't know where I bought it, so the only information I have is the flat measurements. Since it's not a solid object, please allow for some slight measurement誤差. I apologize, but please refrain from price negotiations. m(__)m ① Approximately 39cm ② Approximately 39cm ③ Approximately 23cm ④ Approximately 51cm ⑤ Approximately 7cm (gusset)
