I am selling the supplements from "Tamago Club" and "Hiyoko Club" magazines because I didn't end up using them. The polka dot pouch is convenient for organizing diapers, changes of clothes, and toys. The Eric Carle insulated pouch will be useful in the coming season. It does not fit a 500ml size plastic bottle. It's sized for infant sippy cups and baby bottles. - Size: Polka dot pouch: Approximately 25cm x 18cm x 6cm, Insulated pouch: Approximately 21cm x 19cm x 7.5cm - Design: Zipper closure Thank you for looking.
