4 Reusable Supermarket Shopping Trolley Bags - Shallow 5 "Brilliant shopping aid." 21 January 2018 Bought the deep version of these a while ago. Brilliant concept but too deep for my requirements - gave them to my brother who shops for a family. So glad to have the shallow version of these trolley bags. They're invaluable! Makes sorting, packing and transporting shopping from car to kitchen so easy. Brilliant product. Would highly recommend.
