The case holds the head shells securely in an upright position and includes three UV-Protected capsules to cover the head shells/cartridges. A slit in the side of each Capsule accommodates the headset’s finger lift. Rubber feet on the bottom of the case provide increased stability. Cartridges not included with the AT6003R.
