So, where do you hide your valuable belongings…inside a luxury safe, a drawer or in the secret compartment of your bed? Have you ever thought of using a shelf for the same? Japanese firm Torafu Architects has come up with Clopen, a sleek shelf that conceals a drawer inside. The slim 34mm thick panel has been made from aluminum parts, covered with sliced veneer to make it look like as it was done in natural wood. The ‘Clopen’ opens only with magnetic keys to reveal the hidden 23mm thick drawer. You can use the secret drawer to store your precious items like jewelry and personal documents.
