Kiukivi (eng. fibre stone) is a carbon negative object made of hempcrete – an ecological building material composed of hemp shivs and lime. The shapes are made to hold tiny things – candles, keys, jewellery, a cup of tea – or simply placed on your shelf or windowsill as a totem for ecological and planet-friendly design.

Kiukivi merges ancient material knowledge with a slow design philosophy to meet current values of sustainability.
