I use a green pen on my job, but one that writes well is hard to find in this
area (ball points with green ink skip). Buying these gell refills is more
convenient and less expensive than buying new pens. The ink is a nice brilliant
green and writes smoothly.
Bought these refills (in all colors) for my Pentel Energel pens. Was kinda
skeptical at first, thinking these wouldn't fit or would be of inferior quality
because really, where can you purchase pen refills for $1 (uh nowhere) .... I
was pleasantly surprised when i tried them out. I will definitely buy these
again and I have already recommended JetPens to my nursing school buddies!
