Perfect and great value for money.

The first thing I did when examining these bags is to turn one inside out and inspect the seams. The finish is simply raw edges to butt jointed seams. This is poor, as edges of material may fray, the seam is weak and not resistant to water ingress. Why use a waterproof material if you don't at least bind the seams?

Drawstring doesn't stay closed, lets air in. Bags are useful though for laundry and packing
