The pens seem fine; however when i first tried to write with these none of the pens i tried would work. I returned to the store and was informed that I had to remove the "tip" from the pen. She scraped off a very tiny plastic cover over the tip and the pen worked fine. NOWHERE on the packaging did it instruct me to remove the tip cover. I kept the pens but the trip to the store cost me 45 minutes of driving time and gas. Completely avoidable with better labeling on the package. C'mon Staples. Get with the mfg to make this better.
