Features

Includes Optical Grade Jewel Box

These substrates are specially packaged with the customer in mind.  Each substrate comes in an optical grade jewel box with plastic insert.  Instead of adhering the label on the top surface, the label is placed in the inside top cover of the jewel box.  This way once the coating is applied to the substrate, the same packaging can be used again for the finished optic with a new label.
