Polo Package Update / Development

One of our customer requested the current polo package (box) to be updated.
Previous one had some flaws and issues.
I wanted to avoid any separated pieces, giving it more durability and adding aesthetic features that can express "New" and "Update". 

I explored some ideas and features, sketching through freely.

As always, I make scaled down dummies to double check on the structure integrity and try to find any issues and flaws that the full scaled package might encounter.

Because of their "unique" structures, I had to make many minor changes before I finalized the package design. 
After proving their structural integrity and merit, I made full featured mock-ups right after.
