Thank you very much for viewing. This is a glass food storage container featuring designs of Duffy and Friends from the "white wintertime wonders" period at Tokyo DisneySea. I purchased it when I went to DisneySea. I bought two sets, and I've been using one, but I'm selling the other set as it remains unused. Even with the lid on, you can heat it in the microwave by opening the air vent. This item is already sold out. For Disney fans and Duffy & Friends lovers, how about it?
