If only the key could speak! This instrument that has crossed the ages without a wrinkle, it radiates a number of possibilities and anecdotes so masterful that Martti has decided to grab the key. This rudimentary and luxurious object, devoting a formidable mode of expression capable of upsetting and surprising, capable of audacity and mystery, capable of modernity and archaism. From the simple relief to the rosette of leaves, these keys, all ancient, display a complexity that gives them a lot of seduction. Then, brazed, twisted, folded, accompanied by a handle, surrounded by hinges, the key loses its utility to transform itself into a work of art preserving its identity and its reason.
