Zebra Ballpoint Pen Refill, Sarasa, NJK-0.5 Lead, Black, 10 Count BRNJK5BK

The refills arrived so quickly and the seller included the most perfect origami crane I have ever seen which was a very nice gesture! I had originally bought the wrong refills for my zebra sarasa multi with the pencil, but these were perfect. Be sure to check the cartridge name that's stamped onto them before you buy is the lessonI guess!

Arrived on time and in good condition. Fits the Zebra Multi Function Sarasa Pen. I personally like having multiple black pens and fidgeting, so this works for me.

If I can give a 0 star I would. These refills are a joke. I work in the nursing field. I write but not much. These refills will literally last me 5 days and runs out of ink. Waste of money to purchase.

First refills I have tried (other pen brands) which don’t break after a few uses and ink still in the well. Wow! The ink doesn’t last as long as the original pen wells that came in my pen, but at roughly a buck per pen (when I purchased) it lasts the same amount as a dollar store pen. Pretty happy with this. No skipping, no quick bleed out, writes just as good as the original. Yay!

The Zebra Sarasa multi 4+1 0.5 pens are my favorite. I buy these 10 pack refills. I buy black, red, green, & COBALT BLUE instead of the stock blue. I feel the cobalt blue is a nicer blue color that is clearly blue. Depending on the lighting g paper, the stock blue can appear dark , much darker than I like. Cobalt blue is a more true and crisp blue.

I wish I had known of the Sarasa when I had purchased other pens for grading. The Sarasa ink is smooth, error-free, and vibrant. I doubt I will purchase any other pen or ink refill from here on out for grading. The Zebra .5mm Sarasa multi-pen is by and far the best pen and ink purchase I have made at the price : value consideration.

They didn’t fit in regular pens, they kept sliding on through the pens, they were too skinny for the pens

Really works well though pricy.
