These earrings are printed with an original illustration of a Monarch (Danaus plexippus) butterfly wing on sustainably-harvested birch wood veneer. 

They are 3/32" thick, 1" wide, and 2 1/8" tall without the hook. The hook is antique brass and lead- and nickel-free.

There are variations because of the natural wood grain.
