These markers wrote really nicely. However, they ran out of ink very quickly. I use permanent marker to write the numbers of an address on a box, so it’s larger and easier to see. It helps me to deliver packages more efficiently. With a basic sharpie, I run out of ink after about 50 or so packages. With these markers, I would say I run out just as quickly. That’s disappointing due to the major difference in size. The expectation is that it would carry more ink to be able to use for longer periods of time. There also were a few that came with literally no ink. Like the tips were completely white. Others came dry and they were useless. Being in a warehouse, I don’t have extra time to try to wet it and see if it helps. I say go with a different brand.

With a larger than usual ink reservoir I assumed the pen would last longer. But despite this it last a much shorter time. Using it on a daily basis for 20minutes or so, it lasted a week. I believe the real issue is the cap system does not secure well and causes the tip to dry out early.

Exactly what we were looking for. They do dry up faster than we had hoped, but we got enough pens in the order to last a month or two. We'll go through them quickly, but the price is right.

Excellent product that we use a lot in the Dr. Segnini brand warehouses

They’re a little big to hold, but great markers, work & write big & smooth!

Perfect for using on your moving boxes, or labeling bins for storage. Better than leading brands for the price!
