Interactive Realm Stickers!
I ordered some stickers for various purposes. One to hand out to people as a way of promotion and another to swap with other creators.
Swapping stickers is kind of this inside thing where the creators will usually put the stickers up on a wall that can be seen in their videos. It's like a way to say I met this creator or look at how many creators I know.
I haven't put mine up as of yet, though.
