The energy consumption in the production of a Stelton Shopper is equal to the energy consumed producing 5.23 plastic bags but the Shopper can be used again and again and again it lasts for many years! This means in fact, that after using the Shopper for one week, you make a difference to the climate change. The Shopper is smart and handy and is easy to keep in a pocket or bag. The bag hides away while not in use, folded into its own plastic handle. When you need to use the Shopper, simply pull out the bag, then slide the plastic handle back over the actual bags handles, which avoids the handles from going deep into your hands if the bag is full.
