JANYUN 100 Pieces Ink Pen Refills Replaceable, 0.7mm Ballpoint Pen Refills 107 mm in Length Black Ink Refills Smooth Writing Pen Refills for Journal Writing Office School Supplies (Black)

Purchased these refills for a small pen I keep in my handbag. It was longer than the pen, so I just cut the end to size needed. Works fine.

These inexpensive refills have resuscitated a bunch of souvenir pens that would otherwise have been thrown away. They worked fine with some pens that have 2.5mm diameter refills with the point 7mm long before it fits into the refill tube. Some pens I really like have similar refills, but they are 3mm with a 10mm long point, and these refills don't work with them. Still, it's hard to complain at the price. Some reviewers complain that the blue and black refills are mixed together. In my box, all the blue ones face one way and the black ones face the other.

I have a bunch of Pentel RSVP pens that I love and want to keep using. I also hate buying new pens just to create more garbage. I figured the best solution was buying refills. After searching all over Amazon this item had the best price, most refills and best reviews. As others have said, the tubes and tips are skinnier than usual pens but they still fit just fine. The issue is the tubes are very short. I found a clicker pen where it fits well but the Pentel pens have space left over at the end. To rectify I filled in the left over space. I have been writing with the pens for a few days now. The blue ink does not leak and it writes well. BUT the issue is that the ink sometimes doesn't come to the tip. I have to press down really hard to get it going again. Ultimately it is not a huge inconvenience considering the price and number of refills.

Great Product

We are a few millimeters short to use as a replacement for our existing pens, so I cannot speak out of my own experience except to suggest measure extremely accurately - I didn’t. As for quality, it certainly appears to be, and I wrote with one - ink flowed well, no ink globs or skips. I did not return, because not all pens are created equal - I may find just the right fit, and the price was reasonable.

I can't possibly speak as to longevity as I just began use last week. The writing is smooth. I have not encountered any skips. The listing describes as blue black refills. That does not refer to the ink color (as I presumed) but rather a mix of blue and black refills. I have used as replacements for about 10 ink pens so far. I have not had to trim any refills to make fit. However, even though the length is the same as the original, there is a slight hitch with Bic Click Top pens. You have to press top of pen hard to get ink tip to come out with Bics, and have to press hard to retract the pen tip. I think it has something to do with where the spring lines up on the cartridge. For my other non Bic Click Top pens there are no issues.

Price wise it was ok but you get what you pay for very low quality right very rough will not buy again

Pen ran out of ink today. I took a refill out of this box, popped it in, pen works great. I love these.
