Buy an item, it will pop up in ur storage.
Select/open it then Send to a friend
A good tactics is makeing alt team just to farm you tokens for premium items that you would later on use for your main team.
If you farm for over 10seasons without spending any token you would be able to buy official items for your main team..
even better tactics is to create 3 teams..haha..this way you would have to farm 4 seasons on 2 of the teams to buy yourself official jersey(home & away) of your favourite team and another 8seasons to buy the logo.
Ofc you could just buy them without waiting but that would cost you about 40$.
