I'm considering changing the packaging of my bottled liquid product (2.7 fl oz.) from poly-bags to boxes. I am fully aware of Amazon's FBA requirements when it comes to double sealing liquid products. However, in this case I'm not entirely sure what the policy is. If I place my bottle in a box does it need to be poly-bagged or sticker sealed inside the box as well? I only ask because you never see that with similar products sold on shelves. Thank you.
