This is an insulated lunch bag, perfect for convenience store trips, quick outings, and carrying your lunch. Features a 4-layer insulated aluminum sheet (washable). Size: Height: Approximately 18.5cm Width: Approximately 18cm Depth: Approximately 12cm The outer fabric uses a thick interfacing, allowing the bag to stand on its own. This is a handmade item, so it's not perfect, but I've taken care to sew it carefully. Thank you for your understanding.
