For fellow fans of mid-century design and architecture! I laser cut these three classic breeze block designs from pearl gray acrylic. They hang approximately 2 1/2 inches (and much lighter than concrete!)

I use niobium ear wires because niobium is one of the most hypoallergenic and non-reactive metals available (more so than sterling silver, which may contain small amounts of nickel and other reactive metals).

Have plugs? I can convert these earring designs to use a hinged steel infinity loop that can slide through a standard tunnel plug. This allows you to use your own tunnels that are comfortable for your ears.
