Chalk Ink Extra Fine Tip Wet Wipe Markers (.5mm Tip, 2 Packs)

I loved it at first- when I used it for the first time. I was very careful to keep it capped, as I had read that they dried up. No matter- it dried up- maybe 2 weeks after I opened it. I tried to "revive" it. But- I couldn't save it. I opened my second one, a week ago- let's see how long it lasts. In the meantime, I am looking for something else that will work.
