For people enjoying the pastel work I got these the other day and like them. Enables blending in quite a subtle way and not as messy as fingers or paper stumps (which you have to keep sanding clean) – you do need to wash them occasionally and I have bought two lots now, one for darks and one for lights. Anyway just sharing in case anyone is minded to try…. https://amzn.eu/d/4LetGiL

It’s an Amazon link but I am sure they exist with other suppliers.
