This convenient eco-bag with thermal insulation is the perfect size for use as a sub-bag for lunch or shopping at convenience stores. With a wide 18cm gusset, you can carry your lunch box without tilting it, and it can hold 500ml bottles both vertically and horizontally. (Depending on the shape of the bottle, it may stick out slightly from the bottom width.) The lining uses a cooling fabric, and the interior has a mesh pocket, which further enhances the effect when you put in ice packs. It can be securely closed with a zipper, so the contents are not visible and won't fall out, and it's easy to open and close with a pull tab. It folds up and rolls up, and can be kept compact by securing it with a rubber band. It can be washed (by hand), so you can keep it clean. ◆Size (approx.) W (top) 34 / (bottom) 17 x H22 x D18cm
