I found these at my local Target Dollar Spot. The only kind I found, no other styles or designs or characters. Guess its a good thing I still like Strawberry Shortcake! They fill up very nicely and will fit (2) Lock & Lock sandwich boxes with room to spare, so they are very roomy. Definitely bigger than a traditional Japanese kinchaku. Its made of nylon and has a narrow strip of velcro keeping it closed. They do have flat rectangular bottoms to allow for a flat transport of your boxes or containers.

Worth every penny of the dollar I spent!
