For the dip-lovers and yummy tidbits and toppings enthusiasts, the leak-proof Seal Cup Mini is simply perfect. This box may be quite small, but it's a big help when it comes to packing sauces, dips, dressings and toppings. The round stainless steel food container cup holds 1/3 of a cup. It's the smallest container in ECOlunchbox's 5-piece Blue Water Bento Seal Cup nesting set made from non-toxic stainless steel and food-grade silicone. The Seal Cup Mini nests perfectly inside the Seal Cup Small.
