Regarding the logo size and placement, there aren't any strict limitations. As long as the size fits within the dimensions of the packaging, we're good to go. For instance, with the inner box like Cube 25 mm for 1 kg, where the box height is 21 cm, your logo should comfortably fit within the box layout.Placement-wise, as long as it's on a visible part of the box, we're all set to print it. However, just a heads up, we typically don't print on the inner part of the box, even though it's technically feasible.
