Toolstation used to (perhaps they still do?) sell disposable paint
brushes but they looked so awful that I couldn't bring myself to use
them.

Search Toolstation for
'Use & Thro' Paint Brush
The picture shown is not representative of the quality of bristles.

The trick with these cheap brushes (starting at around 16p each for
12mm) is to give them a haircut with a large pair of scissors before use
to even up the bristles. They are OK for jobs where the finish is not
too important but having said that they perform quite well.

I just throw them away after use.
