### ⭐⭐⭐⭐⭐ 10000% recommend
*by D***N on September 5, 2025*

I love how effortlessly these pens write. They don't smudge and the green is so dark that to an unsuspecting eye just looks black. Can be used for checks or anything else you want. Super comfortable in the hand as well. I keep one in each car and all over the house because I won't use any other pen if I don't have too. I will buy again!
