You have to buy TOKEN with real money and then you can send official as gifts. I tried this too to farm tokens each day... after 3 months I had 100 to buy BVB jersey but can´t send it to a friend. So if your jersey you want to give costs 100 token you have to buy 100 token or more. I guess this is because of that thay are official and they want to prevent that you farm these token with a 2nd account to get this for nothing.
