The box holds a standard 60 card Pokemon deck with card sleeves.
The lid snaps onto the top and should hold on during normal use but is still easy to remove. It has a ledge inside to prevent the lid from being pushed down too hard and bending the cards.
The white bottom snaps onto the black insert and will normally not be removable, but a small amount of super glue will make it permanent if it's loose. The white circle button will need a small amount of super glue to hold to the peg on the black insert.
