I hope they last awhile. At first I thought they were all dried up because they took a couple of minutes of 'pressing the tip' before any color came out. But, they work great on glass with black background at work.
I didn't even know that these existed... Upon receipt, after taking a moment to start the ink flow in the pen, this dry erase pen works great and will fit the need that I have for them perfectly. I tried locating these at numerous stationery stores and failed. Thus, I'm ordering more for 'back up' and 'spares' ;-) A nice WHITE dry erase pen!
I ordered these for work so I could smell a pretty grape fragrance while marking my packages instead of the toxic chemical smells from other permanent markers. These write well on most surfaces but do smudge or rub off on some slicker surfaces but overall I am satisfied. =)
