Use them for alcohol to help control evaporation. I have noticed less condensation in the bottles. It’s very stretchy so a roll goes a long way. Very easy to use, nice and thick material. Good value for the money.

Brittle, constantly snapping. Presumably out of date stock. Unlike any parafilm I've bought in the past, with 1 in 3 strips cut to wrap petri dishes snapping as soon as stretched. Have had to buy replacement elsewhere.
