## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality, just really thin
*by C***S on March 24, 2025*

I was missing informed, well not really mis informed, it just doesn't specify that you have to take cap off top to use the pen. I was hoping for something a little faster like a mechanical or similar. Also the pen is super thin, like half the thickness of a pencil. I have bigger hands and 8ts difficult to hang on to, slippery, but I like the metal casing. Other then that, writes great, both ends an durable product. I would recommend it, but I'd make known the thickness. I'm going to give 5 stars simply because i do.t feel a bad rating is appropriate considering most the bad is my preference.

### ⭐⭐⭐⭐⭐ Almost perfect pen/pencil for my Moleskin notebook
*by L***N on November 22, 2024*

Finally a tiny split pen/pencil that fits perfectly with my Moleskin notebook. The only thing that would improve it is if the pen side retracted somehow or there was another cover provided so you could cover both ends at once. As is there's always a pointy end so not great for pocket carry.

### ⭐⭐⭐⭐ Nice pen & pencil combo but lacks durability.
*by T***D on September 5, 2024*

This pen/pencil combo is a great idea. The size is great for Edc and any use actually. Here's the durability issue only took 4 days for the pen to stop working. The pen was my main use so no more edc for this pen/pencil combo.
