Stickers are intended to shake up the Guild Chat and show emotions that you can't put in words!

Where can I find the sticker tab?
The sticker button is in the bottom right-hand corner of the Guild Chat.

Why do stickers have different backgrounds?
Stickers are divided into three types:
White background: regular stickers
Blue background: rare stickers

Why are some stickers unavailable?
White (regular) stickers become available after you increase your profile level. Blue (rare) stickers can be obtained in special events.
