This is a set of 3 items: a lunch bag, a cup bag, and a lunch mat ^_^ The lunch bag and cup bag are double-layered with lining ✩ The lunch mat is single-layered. The outer fabric is oxford cloth (which has a moderate thickness), and the lining is sheeting. The sizes are: lunch bag, 27 cm wide, 21 cm long, 8 cm deep. Cup bag, 16 cm wide, 22 cm long, 6 cm deep. Lunch mat, 36 cm wide, 28.5 cm long. This is a handmade item. It is not perfect like a ready-made product, with slight misalignments and distortions in the seams. Please consider this before purchasing. Thank you ✩ #lunchbag #schoollunchbag #cupbag #lunchmat #placemat #set
