Bingo Daubers can be changed by using the Inventory button in the top bar. Search for the Dauber that you would like to use and select it. Some Daubers can be used for free; others can be bought with Coins.
VIP and SuperVIP Daubers can only be acquired and used by VIP and SuperVIP players. Once your membership expires you will not be able to use them until you renew your subscription. You will not have to buy these VIP or SuperVIP daubers again.
