## Description

Uni New "Alpha-Gel Switch" Mechanical Pencil has appeared to popular "Alpha-Gel" series. "Uni Alpha Gel" Mechanical Pencil which concentration continues is a series that uses a soft and elastic gel material for the grip part. This time, we will switch between "Kurutoga mode" where the core turns and keeps toggling and "Hold mode" where stable writing feeling is used, and we will newly line up "Uni Alpha Gel Switch" that can be used according to the usage scene. You can switch between "Kurutoga mode" when you want to write beautiful characters with a certain fineness and density, and "Hold mode" when you want to write a lot with a stable writing feeling.

Review: My Favorite Pencil. 10/10 - It's absolutely amazing. Firstly.. I much prefer the gel grip to other pencils. Uni is seriously onto something here. The rotating lead creates such neat looking notes. I've never seen or experienced anything like this. This technology is seriously awesome. You never have to re-adjust. Also.. writing feels differently with it. It doesn't feel like your dragging graphite across a page anymore. It glides. And all of your lines look crisp and clean. The weakness of this pencil is it's ability to break lead. That's really not so much the pencil's fault but if it was upgraded with a sliding sleeve.. that would be cool. Honestly, I cycle between this pencil, the uni alpha gel original, and a pentel orenz nero. The alpha original has a wonderful slim grip. This is a bit on the hefty side with the turning engine. The orenz never - ever - breaks lead. That's because it has a sliding sleeve. It also auto-advances which is awesome. I really enjoy all 3 of them. When I pick up this pencil though, I feel like I'm returning home. The sensation of writing is unparalleled.
Review: Worth what it costs. I got it for 8$ - Really comfortable to hold for either math or writing. I would purchase and recommend this pen. It will feel like quality when your holding it.

### ⭐⭐⭐⭐⭐ Daily Driver
*by J***A on March 19, 2023*

The gel material used for the grip part of the pencil is incredibly soft and elastic, making it comfortable to hold and preventing my fingers from getting tired during long writing or drawing sessions. The ability to switch between "Kurutoga mode" and "Hold mode" is also a fantastic feature. I found that the "Kurutoga mode" was perfect for when I wanted to write or draw with a certain finesse and density, while the "Hold mode" was ideal for when I wanted to write for longer periods of time with a more stable writing feeling. The pencil writes smoothly and the lead does not break easily, which is always a plus in my book. Overall, I highly recommend the Uni New "Alpha-Gel Switch" Mechanical Pencil to anyone looking for a high-quality writing or drawing tool that is both comfortable to use and versatile in its functionality.
