NO BOX for the uni-ball Micro Air Pen
I am changing pens after over 20 years of using a different brand. Somehow ended up with one of these (in black - though blue is my favorite ink color) and liked it so much that when my last "fav" blue pen died; I ordered a dozen of these. Was pretty surprised that they arrived in a plastic bag and not a box. I ordered supplies for a courthouse for years--pens came in a box; so they were easy storage. A Minor complaint as the pen, itself, seems like it could become a "new" favorite! I honestly DO like the way it writes. But, if you are ordering for an office, just keep in mind, they may not come in a box.

Makes fountain pens more everyday
Changing reading to 5 starts. While the ink doesn't dry quickly, the pen is easy to use. These are far less messy that a "real" fountain pen. I like them and will buy again.

Quality pens that people are always trying to steal!!!
Got these gifted from my now ex -wife's law firm, had them for almost 2 years and when a client finally snagged one, I decided to by my own! Worth it and Amazon has great prices for them!
