This is a set of a Mammy Roo pouch and a diaper changing sheet. It was originally part of a set with a mother's bag, but this set has been stored unused. The pouch is a size that can be used not only for diapers but also as a bag-in-bag. There is one pocket on the outside and one on the inside. The size is as follows, measured flat: Pouch: 22 x 15 x 7.5 cm Diaper changing sheet: 45 x 65 cm There is a stain on the inside and black spots on the outside (may be original), so I am selling it at a low price. Please note that it may be folded small to fit within 3 cm for shipping.
