The "Bun Cage" is an original concept and design by Arielle de Pinto for the AdP collection. Hand formed and cast in one seamless brass piece, the 'cage' measures approximately 3.5" in diameter and is 2.5" deep. It holds hair of varying thickness and length well, wound in place and pierced through with the accompanying hand formed and brass cast 6.5" pin stick. Accompanied by a 6.5" brass cast pin. We now offer the bun cages as a set as well, it can be worn in a variety of ways, we recommend very thick/long hair types to purchase two.
