Review: Very useful pencil for drafting and drawing if you need adjustability - I love all the adjustments this pencil allows for. I was able to dial in things just where I like them -- sure it's gimmicky -- and I thought the same until I tried it-- it's gimmicks work for me. It's also an attractive mechanical pencil and feels like an instrument rather than just a writing device. I have MANY mechanical pencils that I have collected over the years. This one is one oof my favorites to hold and play with as I write or draw. I often change up the pencil I am using for drawing or writing, and I keep coming back to this one. If you collect mechanical pencils, you should get this one. If you have use of it's adjustable features, you should get this one. If you just want a good writer or a good drafting pencil, you can get cheaper pencils that will serve you as well or better than this pencil. But for me--I am very happy to have it in my collection.

### ⭐⭐⭐⭐⭐ very nice to use
*by J***S on January 16, 2026*

really nice to draw with and write with, led dispensing length adjustment is cool,

### ⭐⭐⭐⭐⭐ Quality from a brand I know and trust
*by D***N on September 9, 2024*

Comfortable in my hand, easy to use, and very well made. I bought one of their pens a couple of years ago; the Horizon pen. I love it! So, when I needed to buy a dependable mechanical pencil, I knew what brand to look for. Plus, the pencil has some cool features; the eraser cover twists to show in the little window which lead is in it. The tip length is adjustable so when I'm drafting I can make it longer to clear the square or shorter when writing. Great mechanical pencil!!!
