YStudio Classic Brass and Copper Slim Ballpoint Pen
This slender ballpoint pen uses a twist action mechanism.  It’s simple and durable. You can enjoy this pen during your travel or daily use. The color of brass will be changed by different users and various environmental factors, due to oxidation. It will restore its original luster by wiping with copper oil. Without any surface treatment, we hope each product can maintain its individual marks by the constant use of the owner.
