We prove a quantitative stability result for the Brunn-Minkowski inequality on sets of equal volume: if $
>0$ and $
^{1/n}$ for some small $\delta$, then, up to a translation, both $A$ and $B$ are close (in terms of $\delta$) to a convex set $\K$. Although this result was already proved in our previous paper \cite{fjAB} even for sets of different volume, we provide here a more elementary proof that we believe has its own interest. Also, in terms of the stability exponent, this result provides a stronger estimate than the result in \cite{fjAB}.
