The Concave series is a collection of glassware designed by STILLEBEN founders and designers Ditte and Jelena – including drinking glasses, wine glasses, vases, and carafes.

With this design, we were inspired by the craftsmanship of mouth-blown glass. We wanted to emphasise the character of the glass itself as a material—the subtle irregularities, the organic curves, and the way light moves through the structures of the surface.

Each piece highlights the unique expression that only mouth-blown glass can achieve.
