Is a Hermès bag worth less without the box?

Potentially, but losing the Hermès box doesn’t suddenly make an authentic Birkin or Kelly worthless.

The bag itself—its authenticity, model, size, color, leather, condition and year—is considerably more important.

Nevertheless, buyers shopping at the upper end of the secondary market often prefer a full set, particularly when purchasing a newer or unworn bag.

So our advice is simple:

Never throw away your Hermès packaging.
