Yes, this is the same manufacturer that is behind the Posca acrylic markers.

Uni Pin is a solid, quality marker — I’ve been using these on and off for years. Also one of the cheapest in this lineup, though the price difference isn’t huge since most of the markers I use cost between €2–3.50 anyways. I don’t even consider buying anything over €5, unless it’s for testing.

As with many other markers, Uni Pins contain fade-proof, water resistant pigment ink and they too come in many, various sizes. They work nicely together with acrylics, should go without saying.

I’d rate these on par with Stylefile markers (that’s in third place). Yes, they are that good.
