PROBLEM TO BE SOLVED: To provide an openable/closable double box for storing a small article which has a high functionality giving a user a surprise. SOLUTION: The openable/closable double box 10 includes a freely openable/closable outer box 11 and an inner box 20 for storing a small article. The outer box 11 is formed into a heart shape in plan view when it is closed, and includes a symmetrical right side outer box 11R and left side outer box 11L having a center line 15 dividing its lobe part. The box 11R and the box 11L are freely openable/closable about a vertical connecting part 16 connecting them as a center. The external form of the inner box 20 which is formed into a heart shape in plan view is shaped roughly similar to the external form of the outer box 11 which is formed into a heart shape in plan view when it is closed.
