We're shipping our stuff out next week but have a massive collection of perfumes/ cosmetics and quite a few in plastic bottles. I was wondering if anyone knows the best way to pack them? Plastic boxes? And if so where do you get these from?also, we have most of the original boxes, but will we get charged duty if we put half empty bottles back in their boxes or is it best to throw the boxes away?A lot of them are niche/ expensive perfumes so it would be good to keep them but is it best to pack them first or let the shippers do it? Thanks for any help you can give, cheers
