50 Pcs Red Gel Pen Refills with 5 mm Aperture 5.12 inch/13 cm Smooth Writing Pen Refills 0.7 mm Replacement Gel Ink Refills for Gel Rollerball Pens School Office Supplies(Red)

This ink refill is great. The glide that it provides across the paper makes this my favorite writing pen come to life. It's the correct size, and I like that the ink does not smudge but dries quickly. If you leave the top off your pen, the ink will evaporate quicker than normal, so when not using it, cap it. I am glad I purchased this 20-pack supply. It functions as mentioned by the vendor.

I had to do a lot of searching but eventually I found these and they are what I needed

I love these!!! The ink flow is amazing!!! Its a great value for the money!!!

My favorite pen ran out of ink. I tried these: they were the closest to the numbers on what was in my favorite pen and they worked perfectly. It did take awhile to get them delivered, not sure the issue there, but Amazon kept me informed of all delays making sure to ask if I still wanted the product. My favorite pen still writes beautifully and now I can keep it forever!!

This is a really good refill for my pen. It fits great and it writes just as nice or better than the original. I am very happy with this purchase.

These pen refills are great!

Wrong size smaller than I expected.

Why did you pick this product vs others?: These were the closest I could find to replace the empty refills in my favorite pen. They are actually about 1/4” too short, so I needed up attaching a small piece to the top so the pen would work. The only complaint I have is that the ink is not fast drying and ends up smearing on the paper and on my hands.

Durée assez courte mais bien pour le prix

I like the versatility. I use them in three different pens.
