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

These Pentel refills for great to have ready available to refill when in need. With all the writing I do my pens often run out of ink. Having these ready to grab and refill was good to have in stock. The quality is great, very affordable. And for the pens very well. Ink does dry quickly and has a great ink flow.

I am a pen snub and Pentel .07 pens are my absolute favorite pens. I order these refills often. They don’t smear. Would definitely recommend.

Love this ink, I've been using it

I love these inexpensive Pentel gel pens and I love that you can refill them. I use them a lot and these refills are great. The ink is smooth as silk on the paper and the blue color is very pretty. I like my blue more like Robin egg blue rather than cobalt and these fit the bill.

I really like my pens and was happy that I could get refills in blue for my favorite pens. Very affordable and several spares for my two pens.

The refill is good and it writes smoothly. Just it doesn’t work for paper mate pens. It’s a bit big when you try to retract the ink it gets stuck and you have to take the pen apart

This refill rights like butter. Absolutely one of the best ink refills I’ve ever purchased and I don’t think I’ll ever look back.

I fell in love with the first pen I bought and couldn't stand to write with anything else. But having only one pen isn't practical for someone who can't keep up with a high-use item, such as a pen. So I immediately went out and bought 2 more. I used them exclusively and I write a lot. So the other day I'm writing postcards to voters and first one pen runs out of ink, so I picked up the second one and continued. Fifteen words into it, the second pen ran dry. I panicked because I had no idea where my 3rd pen was. So I quickly jumped on Amazon and ordered refills because I knew it would be fast, and it was, taking 2 days to arrive. I found my 3rd pen and all was good. My refills came yesterday but I didn't have a chance to change the cartridge until today. And just moments after replacing them, my 3rd pen ran out of ink. I'm so dang glad I decided to buy the pen and the cartridges are a perfect and cheap way to continue the wonderful writing experience.
