The sea urchin inspired Prickle, from Dutch brand Pols Potten, will look great in your home or (home) office, while merging a retro modern look. The Prickle is woven just like a Seamans Knot, although, in a more elegant fashion - it also looks as if its moving while its sitting still. Sometimes the smallest things have the biggest impact. Dimensions: Ã?18 x H18 cm. Material: Metal. Product finish: Coloured aluminum.
