MengRan 2.75'' Ballpoint Pen Refills,Standard D1 Ballpoint Pen Refill (Remove Blue Cap),Compatible with Swarovski Pen Refills (Blue Ink,Pack of 10)

These fit perfectly & write well. I am pleasantly surprised, given the price point.

Does the job.Fits and performs well.

I had never used a ballpoint pen refill before but my favorite souvenir pen ran out of ink so I had to get refills. The refill was easy to install (just remove the black cap and replace with the cap on the old/existing one - since I'd never done it before it took me a couple of tries but got there in the end, it fits perfectly). I like how beautifully the refill writes. It's smooth and nice, much better than my pen originally was. I will definitely order these again when I need refills again for this pen

I inherited two unusually compact pens from my dad's collection, and these ink cartridges without the caps fit perfectly. I prefer a finer tip, but these still work well for general writing. I don't yet know how long a cartridge will last, but I am working on that because i use one pen often.

Yea, refills from my favorite little pocket pen. You get so attached to your favorite pens. It's wonderful that somebody makes a refill

A+

I ordered these to replace empty refills in some pens I purchased a couple of years ago. The refills fit, the price was great, and I am happy with this purchase.

i ordered a pack of each the blue, black, and red. the blue and black came without the plastic cap, which was great for me since my pen does not need the plastic. the red refills have the plastic cap, and the shaft of the refill is a nano millimeter smaller, and useless in a pen where it just slides in. also, 2 of the 3 refills i tried the red ink doesn't roll. 5 stars for blue and black, wish i could leave negative stars for the red
