This is an OSTRICH skin eye patch, handmade with a dome to allow the free movement of eyelashes. The elastic is adjustable, comfortable and replaceable. It can be cleaned with a damp cloth.

THIS IS A REAL OSTRICH HIDE WITH LEATHER BACKING.  Each patch is different due to the variations in hide.

You will receive one of those variations shown or a very similar pattern.  The crown or back of the ostrich has the most bumps or quill follicles while the sides are quite smooth. The area between is the half quill area where quill follicles are not so dense. The legs have interesting patterns and center wide scales.  
The leather is distinctive for its pattern of bumps or vacant quill follicles, ranging from a smooth field to bumps in varying densities.
