Quality as good as any Brabantia and that's probably all you need to know, though having pressed "Submit" I have just been prompted to write at least 20 words describing my experience with this item and so I should probably explain that they come in a clever dispenser that dispenses the liners much like a Kleenex box spits out tissues, and no matter how many metric tonnes my wife manages to cram into the bin so that the density of rubbish rivals your average neutron star we've yet to have one collapse on us.
These are great! Tough, last well and easy to remove from the bin. Tie handles really work and I've never ever had a bag burst or rip no matter how full I've stuffed it!! Would never buy cheap liners again!
