About this Hermès Constance 18 Black Box

The Hermès Constance 18 Black Box Aventurine is for sale as a one-off piece. The Constance is built around the oversized H clasp, which is the closure and the entire visual statement at once. It is Hermes’ hardest bag to source after the Birkin and Kelly, and it is almost never available at boutique without history.

The 18 is the reference Constance and the size most buyers are waiting on. It takes a phone, a cardholder and little else, which has never slowed demand. Box calf is a highly polished smooth calfskin with a mirror sheen. It patinas deeply over decades and shows every scratch on the way there. Aventurine hardware is set with the stone itself rather than plated, and it appears on a handful of pieces.

It carries the signature H snap closure, an adjustable strap, a shoulder strap, open interior pockets and tonal stitching. The interior is lined in Black lambskin.

Condition is stated as New.
