This is the inner container and lunch belt for a 370ml aluminum lunch box. I am only using the main body, so I am selling these items. I bought it new, took only the main body out of the bag, and the inner container and belt are unused. The design is from Frozen, but I think the inner container and belt from other Skater lunch boxes of the same size would fit. For those who only want the parts, please take them. - Brand: Skater - Product Name: Aluminum Lunch Box (with inner container and lunch belt) ALB5NV - Capacity: 370ml - Features: Compatible with heat retention Thank you for looking.
