I discovered these when I was in art school many moons ago. These are a godsend to creative kids who've been struggling with those horrible, cheap stick markers that come in the "art kits" and such that friends and family with good intentions give them as gifts. You know the ones. You color in a 1/2-inch square and the marker is hosed. These Pentels are great. Vibrant, smooth flowing, easy to use, nice variety of colors. You can't beat them. Pentel has never let me down, and I'm in my 40s. Great stuff.
