## Description

C-307P Ceramic Roller Ball Pen Refill 0.7 mm Blue

Review: Good refill - Pretty solid roller ball refill. Not super smooth but doesn't skip and lays solid consistent lines. Happy with this purchase.
Review: Medium blue replacement cartridge works well - I really like the way my pen writes with the water-based ink cartridge. I've had no problems with ink clumping like it does when using cartridges with oil-based ink. For me, the medium point cartridge writes more smoothly than the fine point cartridge. Also, it's available in blue, my preferred color.

Pretty solid roller ball refill. Not super smooth but doesn't skip and lays solid consistent lines. Happy with this purchase.

### ⭐⭐⭐⭐⭐ Medium blue replacement cartridge works well
*by G***2 on December 10, 2024*

I really like the way my pen writes with the water-based ink cartridge. I've had no problems with ink clumping like it does when using cartridges with oil-based ink.

### ⭐⭐⭐ Received wrong color TWICE
*by E***K on March 19, 2024*

I ordered .7mm Blue and received Black. I'm not going to drive to return this so I just ordered another one... got another Black! FYI the packaging said Blue... cartridge labeling says Black. Nice writing ink though!
