24 Pcs Retractable Black Gel Ink Refills, 0.7 mm Point Black Ink

I love these ink refill cartridges. I journal and take a lot of notes, so writing is an experience for me, not just a chore, and I'm always on the hunt for pens that feel good to use. I've always loved TUL pens, but I hated throwing the whole pen away once the ink ran out, and I couldn't find a refill that matched the original ink's smoothness and depth of color. Then I found U-Right. These refills feel just as smooth and the ink is just as rich as the original TUL cartridges. I've bought both the 0.7mm and 0.5mm sizes. Beyond the TUL pens, I've also used these in my Pentel EnerGel, Pilot G2, and Sharpie S-Gel pens, and they fit perfectly in all of them, plus my titanium bolt action pen. At this point I don't think I'll ever buy a dedicated pen refill from the original brand again. The quality is excellent, they last a long time, and the price can't be beat. If you've got a pen that takes these, I promise you won't regret picking these up. As you can probably tell, I take my pens seriously, and I couldn't be happier with these cartridges.

Glad I discovered these. What a great way to save money on gel pens. Just replace the ink! They fit just like the original ink stems in all my gel pens. Same amount of ink. Good quality dark gel ink. Good price for 24.

Easy great to use, awesome price, writing is like originals, will continue to buy

Very glad to find these refills. They're a bit smaller than the ones in the original Pilot G-2 pens, but OK. I sought them out in order not to add so much plastic to the environment. Throwing away a refill will be much less plastic introduced to the environment than the entire pen casing.

I bought these as a cheaper alternative to refills for my beloved tul pens. They fit very nicely in my tul pen barrel. I like the way they come packaged, essentially each one encased in its own plastic cover. The ink is just a touch lighter than the 0.7 mm blue tul refill. The greatest difference is the friction of the tip against paper versus the tul. The fricture is more- extremely minimal- but if you handwrite a lot, you will notice. Overall, for the price difference, these are a fantastic value and a very good gel ink refill

Very happy with these pens. Go through so many of them. They are a great replacement for Kaco pens. I have the full color set, but use blue the most, so it is really nice to have replacements. Writes very well, and is very satifactory. Unfortunately, certain cartridges were splotchy and didn't work good. I have ran into 2 so far. They are not all the same, consistancy isnt the greatest, which is why I put 4 stars.

Perfect

I ordered these to replace the ink in my Sharpie S-Gel Copper Metal pens based on Amazon and Alexa’s recommendation and did not like them at all. They do not write properly and the ink does not flow well when you’re writing. These refills also come up a bit short so the pen feels weird also. The pen stops writing mid-word. The ink color looks weak and line thickness changes constantly from dark to light as you write. Would not recommend these.
