Creation Guidelines

  • You can now submit your LINE creators' message stickers for review.
    You can release your stickers for sale as soon as they pass review.

    What's special about message stickers?
    - Message stickers allow users to enter a message of their choice in a preset caption before sending the stickers in chats.
    - Users can send long text phrases (up to 100 characters per sticker).
    - Users can enjoy new ways to communicate by sending their messages as stickers.
    - Users can change their custom message as many times as they like after buying the sticker set.
  • You can now sell big stickers on Creators Market.
    We hope you'll take this opportunity to create big sticker sets of your very own.
    Big stickers are large-sized static stickers that are much larger than regular LINE stickers.
    These stickers give users even more dynamic and expressive ways to communicate.
