CYLINT Colored Stainless Steel Fountain Pen

Colored Stainless Steel
Utilizing the World's first patented technology, the thickness of the oxide layer on the surface can be controlled to an advanced level, enabling a rich breadth of color expression on stainless steel.
In addition to the superb coloring, processes that heighten corrosion resistance and antibacterial/antiviral/anti-allergic features have been added, dramatically enhancing the product's value.
On the cap and barrel, we have employed a special stainless steel coloring technology that is excellent in consistent expression of refined color shades, and also gives colors a range of change in tones depending on lighting and angle.
