Zebra Multi Function Sarasa 4＋S Black/Red/Blue/Green Ink 0.5mm Ballpoint Pen, 0.5mm Mechanical Pencil, Black Body

This is an excellent pen if you like the smoothest gel pens but want to carry a multi-pen with a pencil built in. The only drawback is that you need to change the refill pretty often, so order black refills in advance.

Great and corncern seller who reply to queries promptly. Pen design is sleek and nice. Ink quality is good too. Very smooth when writing. Highly recommended!

A great multi pen. Ink flows nice and smooth as to be expected. It would be a good idea to just buy the refills along with your initial purchase. Great variety of colors for all my note taking needs. Love the nice rubber grip as well. Being a multi pen, is a bit on the chunky side, which I like. Skinny pens tend to make my hand cramp. Colors easy to access as well as the pencil, so very easy to use. Huge fan of Japanese stationary, so another fine little pen for my collection!! A++

4 colour ballpoint pen and a 0.5 led pencil all in one.. mind blowing.

The ink in these pens writes extremely clean! All 4 colours plus the pencil are excellent. The only reason I did not give it a 5/5 is because the ink doesn't last really long. I have ordered ten refills each for the 2 colours that I use most, so this should not be a significant impediment. (I also ordered another 6 pens, just in case!) When I find something I like, I stock up!
