Bút Đánh Dấu Sơn Acrylic Màu Đen ARTISTRO 2 Cây - Đầu Bút 3mm Cỡ Vừa - Hoàn Hảo Cho Thủ Công, Dự Án Nghệ Thuật & Nhiều Hơn Nữa

I’ve been using these for a week now and the 3mm tip is perfect for both fine outlines and bolder strokes. The black dries super fast with that glossy, opaque finish—even on glass, which surprised me. They’re my new go-to for quick touch-ups.

The ink lays down so smooth and opaque that I didn't need a second pass on a dark ceramic mug, and it dried to a nice glossy finish in a couple of minutes. For a 2-pack at this price, the 3mm tip gives just the right line weight for both outlining and filling in small details.

I was worried about streaks on glass, but this 3mm tip lays down a perfectly opaque line in one pass, and the glossy finish held up even after it dried. Used it to label plant pots and a mirror, still no fading.
