Ripple marks are patterns left below moving water or wind, and by studying them, scienists can learn a lot about the area's geography. These patterns can tell us about the depth of water above the ocean floor or riverbed, which direction the flow of water or air was going, how fast, whether there were waves or storms, and a whole lot more. 

The Ripple Mark is a capped metal-body pen with textures reminiscent of ripple marks. Use it to conquer your geology thesis or sedimentary research.  

Each pen comes in its own felt case. 

Refill it with our special .7 mm or .5 mm ink cartridges.
