Review on Zig Memory System Calligraphy Dual Tip Marker, Pack of 6 - Pure Black (MS3400-010) by Jennifer Roberts

I use a double-sided illustration marker and it's excellent. The work it does deserves 5 stars, but it does have one downside: the thick nib dries long before the small nib, leaving me with a bunch of pens that work on one end but not the other. I think this could be improved if the manufacturer created separate holes to more evenly balance the life of the spring. So: five stars in quality; Lifespan, three stars = four stars. (I should mention that as a viable alternative, Sharpie makes a chisel-tipped permanent marker that lasts longer and is practically as dark, making it worth carrying with Zig pens. There are also a few downsides here, but you can live with them: Firstly, it is the typically pungent smell that Sharpie and many other permanent markers have, which at least reveals what you are breathing in, and secondly, it absorbs more easily into paper, which means it will seep through to the page below unless the paper is strong enough to prevent it. Based on my experience I think you need at least 80 pounds to be safe. Trunk or maybe less if the trunk is coated. When in doubt, try before you buy.) I think you need at least £80 to be sure.
