Thank you for viewing. The fabric is a firm cotton. It's a bit large, and the straps are made of durable nylon material and are long enough to be worn over the shoulder. The dimensions when laid flat are: width 42.5cm, height 37cm. The gusset is 27.5cm x 15cm. It comes with a drawstring bag that can be folded up small. The fabric is navy dungaree, and the drawstring is also navy. The drawstring bag's dimensions are width 13cm x 23cm. This item was sewn by an amateur using a home sewing machine. I would be grateful if someone who understands this would use it.
