This is a tote bag made from a sumo wrestler's (former Kakuryu's) promotional fabric. The inside is made of #10 canvas, so no interfacing is used, but it has a sturdy construction. (The fabric where the magnet is attached is reinforced.) Inside, there is a three-compartment pocket. It has a magnetic button closure.
