Insulated lunch bag 25x15cm Insulated can strap/ drawstring tote bag/ delicious rice balls

*Upgrade from 2020.5.20 to receive a bonus <aluminum foil upper cover>, which has better thermal insulation effect. Most commercially available insulated lunch bags are made of plastic. We have designed this insulated lunch bag specifically for insulated lunch boxes, which is made of cotton and linen with cotton and a double-layered tin foil insulation layer (commercially available insulated bags are single-layered tin foil Only), the whole concept is to wrap the lunch box with a quilt and add heat insulation. Different from ordinary commercially available insulated lunch bags, this bag has an extra layer of lining, and the tin foil cloth is wrapped inside, so it can also be used as a carry-on bag and can be used to carry anything. In order to prevent the thermal jar from tipping over, there is a thoughtful strap design. / Size/ The internal space is approximately 25cmx15cmx bottom and 18cm high (excluding the height of the drawstring), and the strap length is 36cm The straps can fix thermal jars with a maximum diameter of 9~12cm. / Material/ In terms of material selection, we hope that the bento bag will be made of as little plastic as possible, so we used the following materials: 100% Linen surface cloth, polyester cotton paving, double-layer tin foil bubble cloth, and cotton blended lining , cotton blend handle, Wax rope, covered rope buckle / How to use and maintain / Please hand wash, machine washing may cause deformation. Do not iron as it will destroy the insulation bubble layer.
