The wall sconce “Primary Shape No. 3” is a creation by architect Thijs Prinsen for the Belgian brand Serax. Inspired by reclaimed antique bricks, this rectangular sconce diffuses a soft, warm light. We love its minimalist design, as well as the warmth and texture that the concrete brings. This sconce is available in concrete (gray) and dark red. However, please note that it is not suitable for outdoor use.
