Pencil Holder Secret Compartment

We had a pencil holder to make into a secret compartment. we used 3 staples, cardboard, scrap metal, styrofoam, a button, and string. The styrofoam was made to stop noise. The button and staples made a lock system. the cardboard is the top part of the compartment. The metal was used a weights. The string for easy access. I made this quite quickly although the perfections are much harder so be prepared to tweak at it a lot. Thank you Daniel Hizagrad for the help.
