Parker QuinkFlow Black Ballpoint Pen Ink Refill - Medium Point (3031631PP) | Smooth Writing for Office, School & Everyday Use

What can you say about a refill, excepting that it works with the brand of pen one uses. This refill is made by Parker, for a Parker Urban Pen, which without being expensive, I happen to like a lot. Pen was bought recently, so the refill in mention can only be used in the future when the ink runs out on the pen I purchased. Amazon keeps asking how do I like it, but realistically the refill will not be used any time soon. So based on the pen ink, and the fact that the refill is the same as the one in the pen, I give 4 Stars, hoping, of course, that when I open the refill, which sits patiently for its turn, it will be also a 4 Stars.
