3-Star Review of Artline 90 Permanent Marker Chisel Tip 2-5mm Black Box 12

I like this marker alot, it's very foolproof and writes very dark on: labels, paper milk cartons, books, tape, etc. It has a very useful and sturdy physical Marker Tip that never gets blunt. The only complain that I have is that they don't last very long, and can easily stop depositing the usual large amount of ink if you continually use it in one day/session. If you store it the wrong way, it won't work the best that it can.
