A minor may rent a safe-deposit box or other receptacle for the safekeeping of personal property, or be designated in writing as an agent to have access to a safe-deposit box. In all transactions with respect to the renting of such box or other receptacle, and access thereto, including access by an agent designated in a writing signed by the minor, the minor shall, as between himself and the lessor of the box or other receptacle, be deemed to be of full age.
