Birkin 30

The Birkin 30 is Hermès. It is the size Jane Birkin herself carried, the size the House produces in the largest quantity, and the size that defines the silhouette for the entire family. If you own one Birkin, it is likely a 30. If you're considering your first, this is where most collectors begin.

Because the 30 is used more often than any other Birkin size, the wear patterns are also the most predictable — and the most preventable. A well-stored 30 with proper interior support will look nearly identical after twenty years of daily use. A neglected one shows front-panel sag, corner softening, and handle fatigue within five. This guide covers every aspect of keeping a Birkin 30 in reference-grade condition.
