Leftover paint

[woblob]

We have just done a lot of redecorating and have lots of leftover paint. Some worth keeping as tins are quite full, but is there any way we could store, say, the leftover 500mls we have from the skirting boards without holding onto the full 5L tin? Is there paint safe storage you can buy?

I should say, we live in a flat so storage is a premium! No garden shed/garage option.

I put leftovers in big jars, like old coffee ones, with some clingfilm under the lid. Handy for little touch ups
