MONTEVERDE Ballpoint Refill to Fit Parker Style Ballpoint Pens, Extra Fine, Pack of 2, Blue/Black (P112BB)

I've been searching for a fine or finer-than-fine blue-black Parker refill with no luck, until this item caught my eye. Except for not being a Space Pen pressurized refill (which is what I'd hoped for), it meets my specs, and it's very satisfactory!Edit December 2017: I had one refill leak out the breather port when the pen was stored upside down. It makes quite a mess, and of course the pen was hard to clean up. I'll start plugging the back ends with a toothpick (after making a teeny-tiny breather hole in or next to the toothpick) to prevent a recurrence. There's simply no reason for the breather to be as large as it is. I remain very happy with the refills and am ready to place another order.

The product is a great option. Very smooth and lasts.

After a couple weeks of continyuse I found these to be more or less the same as some of my other fine tip refills. I was really hoping to find something finer than fine but the search continues for me.I also found these tips to be a little scratchy or inconsistent at times with the ink outflow. Maybe I got a newer batch with some faulty tips seeing how other reviews in the past have had mores success than myself.

The color of the pen was more blue than a blue-black in ink color. Nice writing just disappointed in the color

I wasn't terribly impressed by this refill. First, the blue-black isn't really a satisfying blue-black. It just looks like a standard ballpoint blue. Second, I had a hard time writing with it comfortably. It just felt scratchy and would skip often at my normal writing angle, which, admittedly, is probably because of the extra-fine width. I feel like I need to write at an almost 90 degree angle to get a satisfying line. My unbranded Parker refill writes much better, though that's probably because it's thicker. Anywho, I didn't really love it, and I'll probably look for a gel refill in the future.
