Creative packing filler: fake dollars! Tease your friends and relatives!

Want your parcel to deliver an extra dose of humour? First, let your friends and relatives scream with wild joy, then suddenly feel disappointed, then get depressed that they've been fooled, and finally have a good laugh and happily post on Weibo to share your prank with others! It's more fun to use green fake banknotes that look like US dollars at first glance instead of bubble wrap or regular newspapers as filler.
