TecUnite 20 Pieces 2.75 Inch Ballpoint Pen Refills for Diamond Crystal Stylus Pens with Black Velvet Bag Supplies(Black and Blue Refill)

Great value. Fits my Tombo pen perfectly. And they write smoothly. What more could you want, especially for the price.

I was surprised by how smooth and well they write, I have a small 3 in 1 pen and it is very convenient but never used it for serious writing only for short notes and jotting something down. Now with these refills, this little pen will become my true writing instrument! and the price for so many is awesome. I just got it and have no idea how long it will last yet,

These were of the length I needed and write very well. The quality is very good.

These work and fit great with my diamond 2.75 ball point pens. They are the perfect size and made me happy to find them as the pens are small and run out of ink quickly. But I love how they write, fit in my hand, and look. I bought one and was sure they fit well went back and bought 3 more packages.

I have some ball point pens that rotate to advance the refill out for writing. I carefully searched the images, and found this one looked the most like what was in the pen. They are a perfect fit! The company provides a great amount of both Blue and Black refills. So, my amazing rotating pens, especially the laser pointer ones that I cherish, will live on seemingly forever. They place a small dab of glue on the roller ball to keep the ink from evaporating there. Snap that off when uising for the first time, and the writing quality is wonderful. Thanks for supplying them at this nice price

Once I finally got the order, I was glad to get it. This type of refill is not carried in the office supply stores - so this was my only option. But, They seem to be working fine.

Okay refill but a little cheaply made

These were the perfect size for my favorite little pen. I used to use it years ago and was sad looking at it year after year. I finally found the pen replacement for it. I love it, thank you so much for producing this product. You have made a very happy customer!! Cheers!!

Ottimo rapporto qualità prezzo.Tratto deciso e continuo. Consiglio l’acquisto.

Muy bien producto

Die Mienen wurden schnell geliefert, schreiben gut und klecksen nicht.

Le produit est arrivé rapidement et l'écriture est agréable. Je l'ai utilisé pour un stylo rétractable Swarovsky et c'est impeccable.

i bought these refills for my hand made pens, and these are of good quality, and very reasonably priced, they are a perfect fit and easily changed, i cannot say anything about the life expectancy of the ink, as i have just purchased them, but at the great price they will be great 10/10.tony gray
