Scandinavian brutalist glass ashtray, minimalist design, 70s

This vintage Scandinavian ashtray is made of clear glass dating from around 1960. The clear glass offers clean lines and functional simplicity. Originally designed as an ashtray, it can now serve as a small catch-all for jewellery, keys, or other small accessories. Even when empty, it is an elegant object that fits perfectly into a modern, Scandinavian, or vintage interior. I believe (but cannot guarantee) that it is a vintage solid crystal ashtray from the Swiss manufacturer Sarnen (Schweizer Kristallglas Sarnen) from the 1970s-1980s.
