This listing is for a pair of perfect 5/8” (16MM) Gorilla Glass Martele Concave double flare plugs. I wore these often but they were never dropped or damaged, very well taken care of. One side of the plugs are concave with a carved glass texture, the other sides are shiny smooth, clear, and concave. The flares are pretty large at 18MM, I didn’t have a hard time putting them in when my ears were still stretched. These will be sanitized to the best of my ability before shipping.
