The Lego dots set number 41957 features what looks to me like a Staedtler Noris.
Perceptions may vary, so you might not see a Noris there, but with Lego being from Denmark, where the Noris is common, I think there is a good chance that a Noris was the inspiration for Lego’s Dots pencil.
That’s a beautiful find! Did you buy the set?
Strange. I’m quite sure I replied but don’t see the reply now. It was bought as a gift for a birthday party, so the one on the photo was given away, but there’s still another unopened one here. I haven’t decided yet what to do with it.
