Thank you for viewing! This is a tote bag made from a familiar red check fabric. It's also convenient as a sub-bag for school events or work. The outer fabric has interfacing. It's finished with lining and a gusset. The gusset is 12 cm. It's a good size for carrying A4-size files, making it suitable for commuting and carrying documents. Size: Top width: 38 cm Bottom width: 28 cm Height: 31 cm Gusset: 12 cm Please note that there may be slight variations due to the handmade nature of the product. I strive to create each item with care. Thank you for your understanding of handmade items.
