Great collection 😃👌
I remember these multi-colored ones, when I was a schoolboy, I had a few pieces, but I didn't have them in my possession for a long time.
It's a pity that I don't have those pens that have moving details, so when we move them up and down, the details move.
But that's why I have a lot of others, which I will present soon in the January collector's topic 🙂
