ARTISTRO 5 Gold Präzisions-Acrylmarker mit Doppelspitze – Malstifte-Set mit Punkt- und Feinspitze für Stoff, Stein, Glas, Holz, Malbücher –

The dual-tip design is the real win here—I swapped between the 1mm fine tip and the dot tip constantly while working on a glass jar, and both flowed smoothly without clogging. My only tiny gripe is that caps can be a bit stiff to pop off, but once they're on, the paint stays creamy and vibrant.

The 1mm fine tip held a clean line on a glass vase without any skipping, and swapping over to the dot tip for filling in leaves took seconds. Paint dried to a nice opaque finish that didn’t smear once I gave it an hour.

The dual-tip design is the star here—the 1mm fine tip nails crisp outlines, and the 1-5mm dot tip fills in larger areas without me switching pens. I've used them on rocks and a glass jar this week, and the paint stays put once it dries.
