Pentel Sliccies 2 Color Gel Ink Multi Pen Body Component - Clear

It's okay, not too big and writes well, but the barrel broke after a week or so, the plastic seems too fragile.

The size of the pen is great and I love writing with it. It should include the rubber at the bottom for a better grip and make the grooves more defined. I'm ordering a second body because the the grooves where you screw the body together has become stripped.

If you like the way the Slicci pen writes, you will love this one. It is a little thicker making it more comfortable to write with, and you have 2 more colors at your disposal. What a great buy and absolutely fantastic service by Jet Pens staff.

Updating my previous review - the upper half of mine has become cracked right where the bottom screws in, so it won't hold tightly and instead comes unscrewed. The light plastic used for this isn't very durable, but you get what you pay for. I could have kept mine alive a while longer with tape and patience, but I'm trading up to the uniball style fit line instead - I prefer the flow and smooth feel of their gel inks. The feel of this pen is nice and light and it isn't clunky in a pencil bag, but it isn't too durable.
If you find yourself looking at the style fit line, the cartridges are compatible - you just have to use small pliers to pull out the plastic nibs at the top of the slicci cartridges and put them in the style fit ones, since the nibs on the slicci cartridges actually attach them to the pen body. The slicci cartridges work in style fit bodies once the plastic bit has been removed.

Great ink, great writing. But 2 out of 3 pen bodies I purchased cracked :( I'm treating the last one with kit gloves.
