The Sanford pens in our collection have been carefully chosen because they really work!. The metallic and white gel pens don't jam or leak, they flow, opaque, across the page. Signo gel color hold their own against darker papers and the refillable, stainless Sharpie holds a line even a trained artist would admire.
These Uni-ball gel pens have proven to be significantly smoother and more opaque than others we have tried. Particularly dramatic on dark Color Vellum papers. One dozen per box.
