We first spotted these Matryoshka storage boxes designed by Marcel Wanders in Elle Decoration or LivingEtc. We weren't surprised that they're only sold at Habitat, but were surprised to find that they were designed for children. Forget that; we want them for ourselves.

Available in three sets of six, at Habitat. Priced from 65-125 euros per set, depending on size.
