If the Logo on the front is not mandatory, we could put it onto the side where the other logos are.
Please ignore the render quality here
I think the Logos do look quite ok here, also the way they are regarding design.
Not sure about the wand silhouette on the back. Maybe just leave it flat black (break the lines) and put the text there. After all this is only the back and you need to transport the message / text as well with yout product.
