Sanding Marks

Sanding Marks are a good sign a device was remarked. This is caused by multiple reasons including the following:

• Devices were sanded to remove markings • Devices were printed with the wrong markings during manufacturing process and new markings were added
• Devices were remarked and a secondary coating was applied to hide the sanding marks
