I purchased this for at-home IV therapy for my cat with kidney failure. I have used it about 3 times. Length: Approximately 43cm Around the hips: Approximately 45cm Size: MMS Purchased from Neko Bukuroya Fox Family for 8500 yen. You can find detailed usage instructions by searching for it. 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.
