This is an empty bottle case for Recaldent gum. There are two types of openings. Please refer to the photos. I think there are various uses, such as children's toys, making instruments for plays, and water containers for painting. It's a durable and convenient case. Immediate purchase is welcome! *Stored at home. Please refrain from purchasing if you are sensitive to this.* Cancellations and returns due to the customer's circumstances after purchase are not accepted. There are no smokers in my home.
