I love taking notes with these pens! I love how they write and the pen is comfortable while writing for a long period of time. They last a reasonable amount of time, considering the amount of notes I take. They do however, leave a bit empty spots at times, so I have to write over it to fully fill in a word.

Here’s my review of the Pentel EnerGel RTX Black 0.7mm (Medium): I spend way more time typing these days, so I’ve come to really appreciate a good pen, and this one’s a standout. The 0.7mm metal tip delivers a smooth, bold black line that’s crisp and consistent—perfect for notes, sketches, or anything I need to jot down. The gel ink flows effortlessly and dries fast, so smears aren’t an issue, even when I’m rushing. A great pick if you want a quality writing experience!

I have a love hate relationship with these pens. I love the way they write when they work but they don’t work on all surfaces equally. They also don’t last very long. But they are smooth and beautiful when they work!
