Hello
I hope this isn't a daft question...but what type of pens are best for writing on plant labels.
I've tried felt-tips (blurred, wiped off and/or faded very quickly), biro (really hard to get it to write properly) and pencil (variable based on which pencil and which label). Is there a 'go-to' pen type which writes easily, doesn't smudge, fade, wipe off?
I tend to use a combination of wooden, plastic and slate labels.
Thank you so much
