Thank you for viewing my listing among many others! (*^^*) This is a handmade lunch bag with a cute teardrop pattern. ☆☆Please check my profile☆☆ *Size* Height: 20 cm Width: 27 cm Bottom width: 17 cm Gusset: 10 cm (Please note that there may be some slight errors.) The outer fabric is oxford cloth, and the lining is an aluminum heat-retaining/cooling sheet. It can be hand-washed. Do not use a dryer. The fabric is sturdy, so I believe it will last a long time. I would be happy if you liked it! ♪ *It will be shipped folded. Each item is carefully made, but please understand that these are amateur handmade works. If you have no questions, you can purchase immediately. (*^^*)
