Hi,
1. We think there are option to work around without have a simple rectangular box. Please find attached some options to give an idea of the possibilities. Another possible option is for the bottle to lay on top of the sticks so that the width is also reduced.
These are just options to show that we can think outside the box and make it happen.
Regarding points 2 & 3, not sure what you mean. I suggest we can discuss that over video call or so, after we freeze the shape and fitting of the packaging.
Best regards,
