I have always enjoyed using sharpies they were my favorite to use when I had to outline my comics for the journalism newspaper. The comfort, the thickness, smoothness and longevity has always been great. They last for years. I found a whole bucket full in the basement that my dad had used for his glass work and even after almost 5 years of no use they still work perfect.
It's not all black either. They have pretty much any color you can imagine. Blue, green, purple, orange, red, yellow and I think aqua. They lack rainbow lol I enjoy the variation in sizes also. They have king, jumbo, super, regular? and mini. I think that's all but I can't really be sure I'm not the sharpie expert.
Let's not forget the variety. Need to write a fancy message? Grab a fine point. Need to outline some work? Ultra fine point is best. Not many markers comfortable on your hands? Get a Sharpie Grip. Need to write on clothes and not have it wash off? Sharpie Rub a dub. Need to mark on some pouros materials? Yep they have something for that too! Sharpie peel off hydro china marke!
There are many many more because there is a sharpie for every occasion! Any color, any type and all you have to do is add your own personal touch.
