In the product description, if the seller informed that the goods will be sent to you with a box it should be like that, but if it is not specified in the product description, the seller can ship goods in packaging which is safe.
For example, my store, not specified in detail to decorated with box but I"m shipping in packaging safety. Because shipment by retail box. Products will be damaged easily.
I suggest that if you want to get to solve this problem, you should contact the vendor where you purchased the product directly.
Hopefully these suggestions will help you.
