a wet food container designed for bags of pets wet food!!! Just slide one, and the rest will reaccommodate!! :)
After you cut all the parts, just assemble the pair on the sides of the base, then add the front part (the one with a paw) in the front (where the base doesn't have any holes) and add the back part the same way as the sides of the box; it is recommended to use glue for better results.
