### ⭐⭐⭐⭐⭐ want your writing to look better- use this pen!!
*by B***S on August 18, 2021*

I love, love, love the way this pen writes- smooth ink spread with no bleeding, nice glide on paper, perfect size and plastic shaft is able to be gripped well by fingers with no added crap to help you keep your hold. And, true- my writing always looks better when I use this pen (really). its just so darn smooth and seems to last endlessly....I do all my work with it, my spouse uses it for grading papers, taxes and charts and my kids use it in school (when pen allowed). This pen won't disappoint.
