Zebra B-BR-6A-SK-BL Clip-on Oil-Based Ballpoint Pen Refill, SK-0.7 Core, Blue, 10 Pieces

I have a Zebra Zebra Clip-On Multi Color Multifunctional Pen, White Barrel (B4SA1-W) and I purchased this 10pcs box of Blue, also a 10pcs box for Black. The reviewer that gave it 1 star for it not being compatible with his particular pen, a completely different model, is not reviewing the quality of the pen or ink, but his sad experience buying the wrong item. These pens are - by far - the best multi-color (4 colors - Blue Black Green Red and Pencil) pen I have ever used. I recently went through the process to get the old famous 4-color Bic pens (medium point 1mm), which are nice enough but I wanted a finer line and they can be a bit blotchy when ink builds up on the tip. I even tried the Paper Mate InkJoy - which I wanted to like, but it is quite blotchy, a big surprise. It is hard to use it, and if I draw a long straight line it fails to work properly. So I come to the Zebra Multi Color Pen with Pencil... It really is the best pen I have used. I love the multiple colors when I study, using it to underline and circle words in different colors. I even use the blue ink when I take regular notes, since it is such a high quality pen. So I needed replacements, since I use it all the time. It comes in other colors now, quite nice...

My wife thinks I am crazy for getting these refills , but my zebra pens are great quality and are my main tool. I have them in my office and backpack. I never have to lose them because I have them in all my working spaces. The pen mechanism and grip really holds up. Got to keep my pens alive!

Great product. Fit well on the Zebra Clip-on multi pen.

I have used Zebra pens and refills for many years and in general I really like their pens and refills. The box of refills I purchased in October 2024 is different. The blue ink skips and leaves blank spaces. I have tried several of the refills and have the same issue after using for a short time. The way the ink skips when writing makes the refills almost unusable.

Excellent quality pen refills from Zebra and they even have a good number of them for a really great price!

Did not fit the pen I needed it for. I thought the description sounded like it was the right one. I wish it would have fit, it looked like a good refill if it fit!

Doesn’t work for Zebra pens. Missing spring and ridge for mechanism.

I'm on my third refill. All three of them stopped writing after about half way.

Very good quality pen. Have been buying Zebra SK0.7 for the last 10 years!

このタイプのボールペンの芯がなかなか売ってないので良かったです

Exactly as described. Smooth ink. Easy to install into Zebra multi pens.

Llego súper bien y antes de tiempo. Me encanta

As described, works perfect with my Zebra Clip-On Multi.
