A Gacha Sticker Voucher can be traded together with Gacha Stickers for specific Characters at the Gacha or the Gacha Sticker Exchange.
There are two types of Gacha Sticker Vouchers: Gacha Sticker Vouchers and Limited Gacha Sticker Vouchers.
There is no limit to how many Gacha Sticker Vouchers or Limited Gacha Sticker Vouchers you can have.
Gacha Sticker Vouchers vary to Gacha Stickers, in that they can still be carried over after a Gacha ends.
