Black nylon lunch bag with an aluminum-coated interior. It has two layers, so you can put things like PET bottles in the lower section. My husband and I each bought one when they were popular, but we never used them because they were too big, so we stored them. They are new and unused, but they have been stored as they were when purchased. - Color: Black - Material: Nylon - Interior Features: Aluminum-coated material - Size: 300mm x 240mm - Zipper: Double zipper - Two-tiered (both with insulation) - Outer pocket Instant purchase is OK. We plan to ship it adjusted to fit in a post. #DAISO #Popular #TwoTiered #TwoLayer Thank you for looking.
