Did you or the missus pick the bin?
(age old female selection of 'Design over Practicality')
I can't think of any long narrow plastic bags.
I do have an idea for you though:
- Why not just use normal Coop plastic bags (that are obviously too short) in the top.
- Tie them up when they are full.
- Drop them into the bottom of the bin (sealed).
- THEN when the bin is full, dump all the sealed plastic bags into a 35L Züri sack.
- Dispose thoughtfully.
The theory is that the same amount of rubbish stays in the bin for the same time. It's sealed and clean so shouldn't make the bin too dirty.
or, just get another bin.
