Hey, I'm a Brazillian product designer with great experience in bottle and pack design. I can advice you on something unique and very functional. I've already designed milk bottles, shampoo packs, music acessories packs and a lot of other packs and products. I'm a final render 3D professional too, so I can produce very high end renders simulating the real aspects of the final product.
You won't regret giving me this chance.
Regards since Brazil,
Bruno.
