PentelRefill Ink for BL57/BL77 EnerGel Liquid Gel Pen, 0.7mm, Metal Tip, Blue Ink, Box of 12 (LR7-C-12)

Love, love these gel pen refills. The price is great, the quality is great and the quality in the box is great!

Best value for the money,

I love how smoothly & effortlessly it writes, that it’s affordable & the color options

This pen and its ink has been the best I’ve ever used. It always writes well, never going blank until it’s completely empty.Very nice.

Great buy and worked perfectly and lasts longer than the original ink that came with my pen!

I love these gel pens and use them for everything. Unfortunately it was only recently that I learned about refills. Once I learned this, I grabbed every color especially blue, as that is what I use the most in my day to day writing. These are easy to put in and the price is a deal. My only issue with them is they leak. At first I thought it was becsuse the pen was flopping around my bag but now it sits at my desk and still leaks. Maybe it was a bag one? Finished it and put another and that one leaks too. Bummer. It's not the end of the world but my hands def get marked up. Other than that, these work fine.

Interfere are my absolute favorite pen! .07 is the size I prefer. These ink refills are perfect to keep some in your desk drawer and some in your work bag so you always have them. They each come with their own wrap which makes it easy to store.

I’ve had this pen for years. Every time I run out of ink I replace it. This pen and ink are perfection!
