This glasses sleeve is hand tooled with an angled basket-weave pattern often seen in traditional American leathercraft. 
 
To protect delicate lenses, the interior has been lined with a soft pigskin suede suede. The outer layer is made from durable veg tan leather from the Hermann Oak Tannery, well known for its exceptional tooling properties.
 
The brilliant sunburst finish is applied using several pots of dye and a skillfully handled brush to blend them together.
 
This sleeve will provide dust and scratch protection but not crush protection. More robustly built glasses cases are available elsewhere in my shop.
