Thank you for viewing. These are bedwetting support pants purchased from Akachan Honpo. I used to wear them over pajamas when sleeping. Both the front and back are 100% cotton, so they're safe. I used them for about half a year. I didn't have any bedwetting incidents, but it seems like just wearing them gave my child peace of mind. The elastic in the waist is twisted. Please be aware of this before purchasing.
