In the case of ITZY's fan signing event, the gifts are taken back by the fans. Each fan will have their own reasons. Fans usually take gifts to see the members' reactions when they give them gifts or to take pictures of them wearing the gifts.
Sometimes fan sign event is noticed in Fans(ITZY official fan site) like below link. fans.jype.com/BoardView?BoardName=itzy_NOTICE&Num=709&DivisionId=&SearchField=&SearchQuery= In this case, you can apply for a fan sign event by buying albums through a specific link. But, I don't know when the next fan signing event will be held.
