Schneider Topball 850 Black 0.5 mm Rollerball Refills - 2/pk

Perfect! I have a pen that I love and this was the exact refill it needed. Can't get a better deal.

Works great

Perfect fit for a unique pen a purchased at an art show.

I've been using one of these in my favorite pen for over a year now. It's been a great, almost daily go-to and has rarely disappointed me. The ink is a clean black color that writes smoothly and dries quickly. I've noticed as the cartridge has been used more that the roller ball wears out a bit and can occasionally interrupt inkflow. The overall volume of the ink is just fine, but the roller ball has worn out before the cartridge has emptied, which is why I give 4 stars instead of 5. I've already purchased refills because I love the ink despite that one small shortcoming.

A great supplement to the Beil... pen. Smooth writing instrument.

I have a nice older pen that is maybe 20 years old and uses these refills. Think this is only my second time replacing and the refills just work smooth as silk.

Was an exact match to a custom ink pen that was given to me as a gift. Was able to change out the ink and the pen wrote very good, with no smudging.

Loved the pen I've had for years and couldn't find refill. Found it on Amazon and am pleased to be able to replace old cartridge and keep the pen.

No lo he encontrado en ningún sitio, lo pedí con la duda de si serviría, pero por precio tampoco perdía mucho y, arriesgue, me parece un buen producto

Excellent refill for my pen...

Vielen Dank, alles ok!
