The new design, the tin foil inner bag is movable, which can be taken out and put in separately. When using, fold down the two sides of the bag mouth and buckle the buttons, which has better heat preservation effect. In terms of material selection, we hope that the material of the lunch bag is as less plastic as possible, so we used cotton and linen cloth and canvas, plus cotton and double-layer tin foil insulation. The tin foil material is made of double tin foil bubbles, which is different from the tin foil foam on the market (one side tin foil and white foam). The tin foil is easy to crack after foaming for a long time. The double tin foil bubbles are designed with bubbles between the two layers of tin foil. , Use air to isolate the temperature, and the durability is high. / Size / Outer bag size, about bottom 20x16x high 27cm Tin foil inner bag size, about 19x15cm at the bottom, 11cm in height The pattern position of the fabric will be slightly different from the photo because of the different cutting position / Material/ American cotton linen, Taiwanese canvas, water-repellent lining, polyester cotton paving cotton, double-layer tinfoil bubble cloth, cotton blended handle, button / Use and maintenance methods/ Please wash by hand as much as possible.
