A furoshiki is the traditional way to carry your bento box and also serves as a lunchmat and napkin! This one is the perfect size for all the bento boxes you see in this store.
To use, place your bento box diagonally in the centre of the furoshiki, fold opposing corners over the box, tie the other corners together, and you’re done! The top knot becomes the carry handle for your bundle of goodies.
There are various other ways a furoshiki can be tied, and many other uses depending on how it's tied.
