I purchased this for at-home IV therapy for my cat with kidney failure. I've used it about 3 times. Length: Approximately 43cm Around the hips: Approximately 45cm Size: MMS Purchased from Neko Bukuroya Hawks Family for 8500 yen. You can find detailed instructions on how to use it by searching for them. My cat weighed 3kg but was slender, so the bag was large, and I used it with towels inside. Washed. I think it's in very good condition. ■Please refrain from purchasing if you are concerned, as it is stored at home. ■I cannot ship on Wednesdays, Thursdays, and Fridays due to work, please understand. Thank you for looking.
