With 10cm-wide base and side gussets to give more capacity than the flat 'library' bags.
Light 5oz cotton means it can fold up and go in a pocket. (OK, it's got to be a largish pocket).
66cm shoulder length handles.
Big strong stitching means you will have confidence to carry a bottle of wine in this bag (or even something stronger).
Small shop, big shop, big conference, big promotion... this re-usable and eminently keepable bag will be always be there for you and your customers - a 'bag for life'...
