This tie clip has an anatomically correct model of the inner ear, digitally modeled at actual life-size.
The inner ear, a tiny bony apparatus in the skull made up of both the cochlea (seashell spiral) and semi-circular canals (the 3 loops), is responsible for our sense of balance and hearing, and makes a great one-of-a-kind gift for someone in acoustics, audiology, or music.
This tie clip is features the LEFT inner ear / cochlea.
