Bedwetting Alarm *Operation confirmed* Includes two batteries used for operation confirmation. One sensor cord is unused. I received this, but my son refused to wear it, so I haven't used it. The instruction manual has stains. (See image 4) For toilet training and bedwetting prevention. Please understand that this is a used item. Shipping without the box is also possible. If you don't need the box, I'll sell it for 2,300 yen. I will ship it using an inexpensive method.
