I have been using the envirosax since they were first on the market , possibly 15 years ago?
I still have my first bag. It has travelled the world and I use one or more almost everyday.
The amount of weight it has carried would tear most reuseable bags to shreds. Would not go out without envirosax in my handbag. I give them out to friends and they find them indispensable.
Such quality in a pretty package. Live them for myself and for a gift.
