This case perfectly fits a box of 4 Calorie Mate bars. You can carry them without the box getting damaged. This item was created using a 3D printer, so it has the characteristic layer lines of 3D-printed objects. The material is PLA resin. You can take the bars out by pushing them from the round hole at the bottom. We didn't skimp on materials and created it without any internal cavities. Each print takes about 10 hours, so please allow extra time for multiple purchases. Thank you for your understanding. #CalorieMateCase #CalorieMate
