Review on Multicolor 8-Pack Kuretake Zig MS34008V Memory System Calligraphy Markers by Missy Cooper

I bought three boxes of these pens because they have always been my favorite calligraphy pens. I bought the largest color set about five years ago and they are all still in fantastic condition and work well except for the black, red and blue because they are the most used. I decided to buy 3 of these packs so I can have extra spares for the ones I use the most because I figured they would last just as long as the ones in my original set. Here we are, about two months later, and NONE of the thin 2.0mm black pins work anymore. I haven't had a chance to use them, they are kept in my cool dry art room with the rest of my art supplies and they are properly stored on their side to keep them from drying out. But here we are. This used to be my favorite brand but after this experience I don't think I will be buying from them again.
