This is a silicone cap for Richell cups. I bought it for my child, but they didn't use it, so I hope someone else can... It's new, but I've taken it out of the package. Therefore, I've listed it as "like new." Please understand this before purchasing (*_ _) Shipping is planned via Yu-Yu Mercari delivery, and I will use recycled materials☆ Instant purchase OK☺︎︎︎︎ ※ I'm sorry, but I can't offer a discount on a single item (*_ _) Also, I may delete the listing suddenly.
