10 PCS Baoer Blue Roller Ball Pen Refills Push Type 0.5mm Point

No information about manufacturer or the product details.

My riffal s' oder is .50 mm size. But you sand .70 mm size. This is useless. Please. My problem sovel

These are OK, is the best I can say. They feel a little scratchy on the paper and don't write well if you write fast, especially if the paper you're using is slick. The ink doesn't bleed or smear and the flow is pretty consistent, but it comes out slowly, so you have to be a bit patient. I bought these at the same time I bought "Gullor 10 pcs in set Blue Ink Spiral 0.7mm Refill fit to Jinhao, Gullor Rollerball Pen" and I liked the Gullor product better. Maybe if you write slowly and want a more precise line, these are for you. Otherwise, I'd go with the Gullor.

I have been looking for these replacements on 2 expensive pens I purchased in 1992-93. I Finally found these and they worked fantastic. There was some feedback about being dry or old, but I ignored that and found them to be perfect!

I purchased these for my husband. His opinion was brief: "Great! I like 'em!"

Bought these for a Jinhou 159 Pen. Research on Amazon said they would fit. They do not.

I'm pleased with product and will return for further purchases.
