its really thick so maybe a brush would work better than a nib. you can dilute this ink, but when it dries, its not as opaque. the consistency is a bit like syrup, maybe thicker.

It's fun. Tiny origami project fun. It is a really small grid notepad, not really functional for more than that, but it's .....it's a tidbit. That's fun to say, you know it is. Tid bit.

Overall, I love this pencil. I only have one complaint, the grip. If the grip had a softer hold maybe it would get a five star from me. I have a story along with this pencil. This pencil ruined my life. The pencil made me lose my girlfriend, my job and, my social life. I've also gained some weight, due to spending so much time with it. I guess you can say i lost my life because of this pencil. If you want a life DON'T buy this pencil.

Got my Chibi today and my initial impressions are good. While it's not much to look at (I'm not a fan of the fluorescent yellow), it writes very well. It came in a cellophane sleeve with one ink cartridge in the barrel. I loaded it up and gave it a shake to get it started. Ink flow is great...this is a fairly wet pen, which I like. The steel nib is a little scratchy, but writes surprisingly well.
I'm finding that in order to write for any length of time, the cap needs to be posted. It's just too small to write comfortably without it. Of course, that's to be expected in a mini pen. However, the only drawback I've found so far is that when I post the cap, I have to use a little more pressure than I would expect (and a little twist) to get it to stay secure.
If you're on the fence, buy it. For the price, you can't go wrong with the Chibi. Stick one in your pocket or purse and if it gets lost or given away the branding on the cap might direct someone to the best pen site on the web and you'll have done your good deed for the day. Win/Win.
Way to go JetPens! (Now, let's talk about different body colors....)

dries in about two to five minutes depending on how thick you drew. it also works with copics so thats good.the ink is not waterproof, but i never use water colors so...

i think its worth it.
