I really love staedtler. I know from my old hand drafting days, that they make a sturdy, high quality product. This applies to their art supplies as well, which I have a ton of fun with (watercolor markers, India ink brush pens to rival Faber-Castell!! I came across this Noris pen on a deal to good to pass up. I got the whole box on a blowout, for under $2, less tax!!This marker is very high quality. It glides across canary, trace and bond paper. It writes smoothly in my planner, my diary and draws fine in my sketchboo! I know it's purple, but it's fun... I would have scooped up more if that same price translated to black also... However, I don't even recall seeing black, so I'll have to keep checking back. Either way, it's a great buy!The caps click on tight. You can even store it on the end while you write, but don't leave the cap off overnight or you will find it all dried up! These will last a long time, even with daily use. I've had some staedtler pens for almost two decades and they still write - though, maybe not for long. I would definitely buy these again, in 15 years when they die of old age...
