WHEELY GOOD PEN!
I use a car tyre paint pen (from www.amazon.co.uk) for my plant labels, it won’t fade or wash off and adheres to most labels. It also comes in a variety of colours.

I use a piece of fine ‘wet and dry’ sandpaper to clean plastic labels. Dip the sandpaper in some disinfectant beforehand, so it cleans and disinfects them at the same time, removing the risk of spreading disease. The labels will then last for ages.
