I came up with a "Tree Supermarket" design and had them locally screenprinted on blue and magenta baggu bags. They hold up to 50 pounds and holds the contents of 2-3 grocery bags. They are made from 100% Ripstop Nylon and fit comfortably in hand or over the shoulder.
15.5" wide | 25.5 " high | 6" deep. Folds flat into a 5"by 5" pouch.
Handwash gently, inside out.
These bags are currently available in my Etsy shop: here
