Best pens i ever used, for one they dont skip...period. the ink is bold and line is thicker than normal pens. These are my new go to pens for everything.In my picture im showing a regular pen on the left, on the right are these pens. Smooth glide, bold line, never skip. Fyi... You may need to wipe off the ink tip once in awhile because of ink buildup, but its not a big deal. And for storage, its best to lay flat.
