This is an older page doll I received from https://twitter.com/powderedf Penelope is wearing a pair of training pants to avoid wetting the bed. The particular one she is wearing is made by a company that specializes in health care, and they carry these training pants in pharmacies and medicine shops. Penelope tried the training pants with the girls' designs before, and this time she wanted to try out the boys' designs. It appears to have good absorbency, and they don't leak much. It could hold 2,500 milliliters of urine, provides 12 hours of protection, has stretchable waistbands with re-sealable velcro tapes on the sides, a blue star-shaped wetness indicator on the front, and come in sizes 4 and 5.
