Do NOT buy
I have tried unsuccessfully to open and unwind this foil. It is now in the bin. I have scissors and a knife. I will never purchase this again.
This is basically Tesco Value Foil repackaged iand charged at 1.5 times the price (because the value foil was 15 metres rather than 10) .
I like this because it is really strong and I need less to line a tin and it is easier to work with.
