Pentel 5x EnerGel LR7 Roller Liquid Gel Pen Refills,Black Ink, (0.7mm), Metal Tip, New (Refills BL497, BL417, BL407,BL107,BL77, BL57 and BL37)

The ink quality is the best allowing nice smooth writing with no leakage and the cost of the refills is very reasonable!

I was gifted this pen earlier this year and fell in love with it. It glides so smooth and the ink is wonderful. It ran out of ink so I purchased these refills and they fit absolutely perfect and a great value. I wish I could’ve found the ink in purple or light blue.

These work great so that you don't have to keep buying new pens. These refills are so flowy and write so well!! I will rebuy for sure

so far so good

These are very reasonably priced and work well. However, they don’t work upside down. Still satisfied.

Good value and less waste in buying a whole new pen. I’ve reordered many times.

I have a gold EnerGel pen that I have had for approximately 4 years now and I just started graduate school. I needed a good pen for school and I picked it up again after having not used it since my sophomore year of undergrad. The ink had dried out and was no longer of usable quality so I found this ink replacement in hopes that it would fit the pen. It fit the pen as expected and the ink is as smooth as I remember it being, it’s such a nice pen and the ink flows so wonderfully. Highly recommend this ink for any pens that fit it, you will not regret it.

I like that the ink is blank, and it writes smooth! It is easy to refill my most favorite pen.
