Flexible Joinery is a clever creation from israeli design lab Dag. The idea is to provide a temporary and adaptable joining function, which can serve many purposes around your house. Made out of a silicone casting over an inner metal skeleton, these joining elements are flexible and strong at the same time. The technology dates back to the 1950′s, with Bruno Munari’s ‘Zizi the monkey’. According to Desingboom, the pink color of the elements is meant to give visual contrast against wooden shelves.
