Free Coins are Coins that are given free of charge that you can use to unlock WEBTOON content.
We occasionally have promotional events where we may give users Free Coins. You can use Free Coins the same way you would use regular Coins to unlock episodes. Please note that Free Coins are used first in the event you have both Free Coins and Coins from a previous Coin purchase available.
You can see when your Free Coins may expire by going to 'MORE' and clicking on your Coins. Under your Free Coins, the expiration date will be displayed where it says "Valid until: 2025-X-XX, 09:00"
