### ⭐⭐⭐⭐⭐ Review
*by H***T on 12 August 2024*

Absolutely in love with these pens! I usually use these for artwork and occasional notes. I got one for a gift last year and loved it so much I had to buy more. I love how dark the ink is and how smoothly they write. It does have a little bit of dry time (like most gel pens) so be aware of that. Definitely worth the money. Decent grip and size, great performance. 10/10 recommend
