Blue Ink Refills (6pcs), Replaceable Ballpoint Pens Refills, 1mm Medium Tip - Blue

Exactly as they should be as a replacement. Well made, work great, fit perfectly. Great price.

Good. Works as they should. Fits as they should. No issues.

Write smothly, compatable with numerous pens from Europe and the USA. Easy to install.

Probably really good but didn’t work with any of my pens.

I have a favorite pen and the ink cartridge Ran out . I thought I had a replacement Unfortunately I had not. So I used the camera in my Amazon app and took a photo of my original cartridge and this came up as a possibility as a replacement. It was perfect exactly what I needed . works just like the original

I need it for a replacement for a technical pen the tactical pen is waterproof but the waterproof refills just for one is 10 bucks wasn’t gonna pay that price for just one cartridge this six piece insect seems to work very well and it writes very smooth

They fit perfect and write medium easy to refill the pen I have

Easy and inexpensive way to keep pens in use.

Bought this as a gamble for my tactical pen that came with my dumbwatch (call it that my Spyware app watch from china that isnt lasting long looks like) anyways bought it as replacements for the blue ink it came with to find it fits perfectly with the tactical pens (my version just has a window buster at end all black) will buy more as I only write in red at work like I'm writing in my own blood

The first one (of 6) fits well and writes smoothly. I am a happy customer.
