The skip bag in picture was used by the shop behind for a complete new shop fit out. We then just pulled the bag outside so I could crane it away. Cant do any of that with a metal bin. For a start with us keep the skip for as long as you need it for, no time limits with us. Takes the same junk, if you zoom in you will see that with this bag. So easy, user-friendly, cost effective, and sizes to suit
