JANYUN 100 Pieces Ink Pen Refills Replaceable, 0.7mm Black Ballpoint Pen Refills 5.5 Inch in Length Black Ink Refills Smooth Writing Pen Refills for Journal Writing Office School Supplies

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.

very handy for office pen replacements

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.

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.

Overall very good. I thought I was getting a blue black ink color, but there are some blue and some black inks so don't be fooled. They do write fine and are a great value and you'll have ink for your pens for years! or at least a long time.

Great Product

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

[CORRECTION: THESE DO NOT FIT THE PEN I ORDERED WITH THEM, THEY'LL FIT OTHERS THOUGH, THE STATEMENT APPLIES TO THE ROLLERBALL REFILLS I BOUGHT WITH THE PENS, SEE THOSE REVIEWS] OTHERWISE, SHOULD WORK FINE. REQUIRES SPRING, FOR "CLICK" KINDS OF PENS. QUITE A FEW FOR THE PRICE.

Kuliminen, Hälfte blau, Hälfte schwarze Tinte, sreibt gut, kleckst nicht

As described. Quick delivery

Perfect quality and works with most type of pens

Fast shipping. I don't know what i'll do with a hundred refills but I'd like to think that I'll never have to buy a pen again. Fits my favourite pen. (with a little trim) Writes nice. I like it. This is a good buy.

Sensationell schnell und gut!
