You can easily trade stickers using our Safe Trading Feature! :) More info about it here

If you have more than one copy of the same Sticker, you can send them to a friend and help them with their progress.

In the Album menu, the Stickers you have multiple copies of are marked with a "+1" (or a greater number, if you have more than one extra copy).

To trade an extra, tap on the Sticker you'd like to trade.

At the bottom of the Sticker, you will see a “Send” button. Hit that button, select a Friend, and send the Sticker on its way!

Remember, you must be connected to Facebook if you'd like to send Stickers!

Keep in mind that there is a daily limit trade of 5.

You can also exchange excess Stickers for a reward using the "Reward for Extras," found within the Album menu.
