I work near Daler-Rowney in Bracknell and I have been lucky enough to see a new product.

It doesn’t look like much, but this paint tube is very special. It has a left-handed thread screw cap. Lids that turn in the opposite direction has now been scientifically proven to move paint and stop it drying and sticking the lids shut.
I didn’t believe it either. But it’s true. Why has nobody thought about this before?
Check it out on the Daler-Rowney website.
