Cross Refills Blue Dual-Pack Rollerball Pen - 8521-2

Excellent Quality and Smooth Performance! I’ve been using Cross ink cartridges for a while now, and they never disappoint. The ink flows smoothly and consistently, producing clean, sharp lines with no skipping or blotting. It dries quickly, which helps prevent smudging, and the color is rich and vibrant — perfect for both professional and personal writing. What I appreciate most is how easy the cartridges are to install; they fit securely and last a long time, offering great value for the price. Cross clearly maintains a high standard of quality with their refills. Highly recommended for anyone who values precision, elegance, and reliability in their writing instruments. It truly enhances the writing experience!

Excellent ink cartridges at a great price

Great quality original Cross refill. Fast shipping and good packaging. Would recommend.

These cartridges write smooth and clean with no skipping. They snap in easy, no mess, no guessing. The black ink is consistent and dries fast enough not to smear. If you use a Cross pen and want cartridges that just work, these do exactly that.

I always use cross refills, they are very good, very reliable

It was excellent

An awesome black ink. I accidentally found this one when I was looking through some old pens I had. I found a basic old cross fountain pen and a cartridge of this ink. Put it in and the pen wrote like a much more expensive pen. Smooth, wet flow. Dark black color. It does take a little time to dry, so be careful of smearing. My new favorite black.

I love my Cross pen, and when I needed a refill I discovered that ONLY Cross refills will fit, and I tried a LOT. Now, they're perfectly fine, but I think it's kind of sneaky on the part of Cross, though a clever marketing strategy. Maybe there are a few off-brands that will work, but I haven't found one. That's OK because the refills are as high quality as the pens. Gel pens can smudge, but Cross dries fast. The color is a dark blue (not blue/black) and it is easy to write with; the pen pretty much glides across the paper. It's worth it.

Il prodotto corrisponde alla descrizione, tratto deciso e molto scorrevole.

This is a wonderful ink colour that flows very well. I love it and had no issue with opening the bottle as some people supposedly have. You won't be disappointed.
