This is a set of 36 different colored dual tip set art marker pens that are 100% acid free non-toxic water based watercolor markers that you can use for adult coloring books, drawing and writing. These dual ended markers have both 0.8 mm fine and 1-2 mm brush tips. The fine tip can be used for sharp, precise lines which make them the perfect option for illustration, calligraphy, or coloring and the brush tips can be used for outlining and detail providing great versatility and flexibility o create various styles, sketches and patterns. They have a rounded shaped barrel design that is slim and will fit comfortably in your hand. They have caps that are true to their pen color and that are easy to remove and replace so the ink will last longer and not dry out. They are made out of high-quality quality materials that are strong and durable so they will last for a long time. I really like these dual-tipped markers and I would definitely recommend them. Kids as well as adults will like them. They will make a great gift.
