Touch up stick

Can anyone recommend a supplier please? Thanks

I've used this company for car paint but they don't sell the pen style touch up paint.
I use a tooth pick or pin for small stuff and a thin paint brush for larger repairs.

Choose Car paints from the UKs biggest online colour database

Halfords may sell the touch up pen in the colour your after if it was used on later cars?

If it's only a stone chip repair and the colours not 100% I'm sure you won't see it?
