* Upgrading from 2020.5.20 and adding <aluminum foil cover>, the insulation effect is better. Most of the materials of commercially available thermal insulation lunch bags are made of plastic. We designed this thermal insulation lunch box special for thermal insulation lunch box, which uses cotton and linen cloth, cotton spreading and double-layer tin foil insulation layer (commercially available thermal insulation bags are single-layer tin foil That's it), the whole is the concept of adding a layer of quilt to the bento box and adding heat. Different from ordinary commercial heat-preserving bento bags, this bag has an extra layer of cloth, wrapped in foil cloth, so it can also be used as a carry-on bag and can be used for anything. In order to prevent the insulation tank from toppling over, there are intimate strap designs. / Size / Internal space about 25cmx15cmx bottom 18cm high (not including the height of the beam cloth), the strap length is 36cm The strap can fix the insulation tank with a diameter of 9 ~ 12cm. / Material / In the selection of materials, we hope that the less the material of the bento bag, the better the plastic, so the following materials are used: 100% cotton and linen table cloth, polyester cotton spread cotton, double-layer tin foil bubble cloth, cotton blended lining , Cotton blended handle, wax rope, wrap rope buckle / Use and maintenance methods / Please wash by hand, machine wash may cause deformation.
