Zebra Sarasa 3+S 3 Color 0.5 mm Gel Ink Multi Pen + 0.5 mm Pencil - Transparent Body

This pen is the best I've used for a multi-pen. I write medical records and need the three colors and a pencil. The gel ink is very good and once it dries, it is waterproof. I order them as gifts for my colleagues and everyone loves them. The refills are always perfect as well.

This multi-pen performs well; each ink and the pencil slide smoothly in place with a barely perceptible click. All of the inks are smooth writing with no skipping. If you need 3 colors of gel ink AND a pencil in one instrument, this is your pen+pencil.

The grip is very wide but that is to be expected in engineering an instrument that has 4 choices. It will take some getting used to. I still need to incorporate this into my "daily arsenal".

contrary to what the review above said this pen writes very smoothly. it feels so light almost like you are writing on air. definitely one of my favorites. Also writes dark another plus.

If you are after dark ink this is the pen for you. It does not write as smooth as other gel pens. The grip seems bigger than other Multi-pens.

This *is* my pen. I bring it everywhere with me, and keep a backup as well.

The line is ultra-thin, and completely *solid.* It photocopies perfectly.

This pen excels at detail: *schematic work,* *logging,* and *annotation.* The small line means that you can fit in entire paragraphs between lines of print-out, or clearly record small log records with great information density. When working with diagram and schematic, you can modulate size cleanly, with no loss of quality. Because red, blue, and black are quickly available, you never have to reach for another pen -- until you want something in bold text.

I have never used the pencil, and wish instead that I could use green in its place. However, if you are exclusively doing schematic work, I can see how the pencil would be invaluable: You can pencil in how things should be, correct mistakes, and then pen in afterward, all without moving your hand from the drawing surface.

My only serious complaints is with the eraser: It is tiny, and only a small portion of it is usable without actually removing the eraser from the top of the pen.
