This is a set of 3 items: a lunch bag, a cup bag, and a lunch mat ^_^ The lunch bag and cup bag are made with a lining, using two layers of fabric. The lunch mat is made with a single layer of fabric. The sizes are: lunch bag, 27 cm wide, 21 cm long, 8 cm deep. Cup bag, 16 cm wide, 25 cm long. Lunch mat, 36.5 cm wide, 28.5 cm long. This is a handmade item. It is not perfect like a mass-produced product, and there may be slight misalignments or distortions in the stitching. Please consider this before purchasing. Thank you! ✩ #lunch bag #school lunch bag #cup bag #lunch mat #set #baseball #boy
