The case is made for the international booster box of 36 packs. Inside, it measures 140 x 79 x 126 mm (width x depth x height).

156 x 89 x 142 mm (width x depth x height). Use that figure when you measure up a shelf or cabinet.

A sealed box that has been opened is no longer sealed. In a case you handle the acrylic rather than the box, and the box stays closed until you decide to open it.
