Review: Very professional, well made, and comfortable- easy to write - These pens are my go-to writing pens. I love how balanced they are holding, and the quality of the smooth writing. And the material and workmanship is above the rest and will keep them on hand. I never had any smear marks and the ink dries quickly. I use many colors and they come a variety of colors. They work well on my professional documents at work and I carry more then two with me at all times. They are perfect during daily use for many days and months- thank you!
Review: A Great Purple Pen - This is a great pen. The ink glides across the page and there is little to no smudging. The pen is a great fit in my hand and I don't get fatigued using it. The pen is easy to use, and purple is one of my favorite colors. I wish the price was a little lower, but it is still a good price for the amount of pens that you get.

### ⭐⭐⭐⭐⭐ Love
*by K***R on October 16, 2025*

I love these pens & I love the fun purple color! 0.7 is the perfect size/weight, smooth writing & as a lefty a good pen is always a bonus! Decently quick drying but might smudge a little if you’re not careful but it’s still worth it!!
