I was skeptical about paint pens for glass, but the 1mm fine tip glides on smoothly without skipping, and the dot tip makes filling backgrounds ridiculously easy. Everything dried fast enough that I didn't smear a single line. Definitely grabbing another set for my students.

I’ve been using these to decorate small wooden ornaments and the 1-5 mm dot tip makes filling in those round areas so much neater than my old brushes. The paint dries fast enough that I can layer colors without waiting forever, and the fine tip handled the lettering perfectly.

The dual tips are a real time-saver—I can outline with the fine point and immediately fill in with the dot tip without switching pens. The acrylic coverage is solid on wood and glass, though I did need two coats on darker surfaces for full opacity.
