Then you will be ok. As long as you dont order outside the Schengen Area, packages are discretely packaged. Even if opened by the postal service, the boxes are labeled as skin care or hair care products. When you order outside, such as India, Singapore, USA and it has to clear Customs, they might check the box.
Also ordering from the UK since they left, a ton of packages now get opened.
If your package gets opened or you receive a letter to come to the post office to open the box before claiming the item, just dont go. They will either toss it or return to sender.
Buying and shipping inside The Schengen Area to Italy = Safe.
India, UK, Hong Kong, Singapore, USA to Italy = Not Safe.
