This set includes 22 high-quality acrylic paint markers with a 3mm medium tip, perfect for a variety of creative projects. The pens come with five extra replaceable nibs for extended use. Suitable for arts and crafts, stones, photos, mugs, canvases, pottery, and almost any surface you wish to decorate, they also work well on shirts and shoes. To ensure optimal performance, shake the pen with the cap on, then air out by pressing the tip upright to release air. Press the tip on a soft surface until paint flows, and test on paper before starting your project. After use, cap the pen tightly and store horizontally. The set features a range of reds from warm to cool tones, pinks, and mid to dark browns. Made with water-based, non-toxic, and acid-free materials, these quick-drying markers are safe and conform to ASTM-4236 and EN71 standards. For permanent results on glass or ceramic, bake at 350°F for one hour.
