The second Benicar pen I've picked up. See the first one here. This one is actually quite nice. Taking it apart, I found the ink cartrige advertised free refill cartriges, which was the first time I've seen this. I guess they want to preserve the lifespan of their little advert.
A quick visit to the website which supplies the refills discovers they actually cost $3.95, for shipping and handling. No, thanks. I got the pen for free, I'm not investing in the product.
