EnerGel® Liquid Gel Pen Refill, 0.7mm, 2 Pack

I love the pens that these refills work in. This pan of these in refills right so smoothly. There's also an environmental concern. It's better to buy the refills and throw those smaller items away when you use it all up than an to pay more for entirely new pen and throw it away every darn time!

I am satisfied with the quality of the product
