Uni-BallJetstream Fine Point Roller Ball Pens Refills for Multi Pen Type -0.7mm-black Ink-value Set of 5

This is exactly what I needed. Make sure the model number is the correct one (SXR8007).

I ordered these refills for my Jetsteam 3-in-1 ballpoint pen and they're exactly what I needed. The ink is wonderful (my favorite) and they are super easy to install in the pen. Great value for your money as well.

These pen refills do not fit the pen they are designed for. The description is false. They are very very short . Cut too small! and now not returnable. Even though in my opinion they are defective. Just go to Stapes and get the refills

I saw a lot of reviews saying that the cartridges don't fit, and I was worried. tl;dr: Can confirm that this fits the MSXE510005.24FYI the MSXE510005.24 (not the product being reviewed) is shipped with 0.5mm cartridges, but I had trouble with smooth writing with the black cartridge, so I bought these to replace it. This 0.7mm cartridge writes well without skipping. It isn't individually packed as pictured in the product page, but rather in a small plastic bag. I don't really care about the packing as long as the refills work. These will most likely work with the MSXE510007.24 too because I'm pretty sure the body of the pen is the exact same.

Great value, but b wrong refill for my clip-turn multi...will use for something else...

I have a multi color jet stream pen that I use for work as a nurse. This pen/refills write very smoothly and do not run or smudge. Important for lefties.

Does not fit Retractable (RT) model, after some research, I believe it fits the multi color pen.

I had ordered three similar black ink refills for my pen before I found these ones (the right ones). The other ones I ordered were either too short or too fat for my pen. These refills are perfect--easy to replace, smooth to write with, and at a good price.

Refills for Jetstream uni multi pens. These are .7mm which is the standard size in the normal Jetstream pens. The ones that come pre installed in the multi pen are thinner and feel scratchy to write with.

One of the best !!!

Ordered for my son, he loves it.

Too expensive

I initially wrote this a 4 star review because uniball jetstream inks are my fav. but then after couple days of use the first refill dried out. I stressed over every single method to get them going again and then found that a flame from a lighter for 5 seconds on the metal tip restarted it again. Then I wrote a few more lines only to have it dry out again. I'm really sad about this because all the other colours that came in my uni multipen 4 in 1 don't dry out at all. Only the black one keeps drying out. I have to keep a lighter on my table to restart the pen every minute and it is very annoying. I can't even focus on my work properly anymore. :( i just want to write with a good ball point pen thats all :(
