Ito En Mugicha "Okiagari" Cooling Cushion. - Brand: Ito En - Product Name: Kenko Mineral Mugicha "Okiagari" Cooling Cushion --- This is a product I received at an event. My child enjoyed playing with it, but seems to have lost interest, so I'm putting it up for sale. [Features] (Photo 3) You inflate the cushion with air. (Photos 4-5) You fill the cushion with water at the bottom. Then, it stands back up even if it falls over. However, it won't stand up if it falls completely flat. [Notes] The jack came off shortly after I received the product (Photo 6). Because of this, my child was playing with it without the cover. I think it's best for those who can fix the jack or don't mind it to consider purchasing. Thank you for looking.
