EUC This was originally a box of 24 but there are only 11 available. I have tested both ends of each marker and they all mark perfectly with rich ink and no feathering of the ends (see photo of color swatching) Double ended The ink has minimal odor, which makes it ideal for prolonged use. The double-ended marker has a small nib and the other side features an ultra-fine tip. The ink is formulated to give the richest color saturation with silky smooth coverage.
