Theres a product, well a range I am looking into importing, its unbranded and comes in plain cheap looking boring tacky pacakging, obviously china lacks style

anyway, what are your thoughts on getting your own packaging made and repackaging potentially hundreds of products if they add value and brand to the product. Would you do it yourself or ask the manufacturers if they could? I dont see how the latter would work though, do they buy in their packaging from other factories?
