If you liked my last bin that's great because this one is better!! It is designed to fit in thin but tall places. There are two halves plus a ring to keep the bin in place. It stands around 30cm high, 20 long and 9 wide. The bag goes in and the ring clicks into the groove on top holding it in place. When the bag is full remove the ring and tie up the bag. Then the top half of the bin un-clicks from the bottom half to easily remove. The top half and bottom half easily pice together as too the ring to keep the bag in place. Print out all three pieces and you're done!
