Did you know that the microns can leak if they are shaken up? It sometimes happens during shipping, from the package being thrown around (the mail/UPS people are probably about as gentle as the luggage handlers at an airport!) But they can also start to leak if YOU shake them. If you're the kind of person who talks with your hands, you should make sure you're not holding a Micron when you talk. Here's what my pen looked like.
But did you also know they can be cleaned and almost always be perfectly fine to use again? Wash off all the ink on the pen, then rinse out the inside of the cap. Use a q-tip to wipe around inside the cap, rinse again, and keep doing that until the q-tip comes out clean. If you don't clean out the cap and just put it back on the pen, it will get all inky again. I've saved a few pens by following these steps.
Here's hoping that you don't have to clean a leaky pen too often!
Thanks for the tip Caren..
