This is an official, authentic product. It is currently discontinued, making it difficult to obtain. This is a blanket from Genshin Impact's Lantern Rite event. Feel free to apply immediately if you have no questions. It will be packaged in OPP and shipped via Rakuraku Mercari delivery. Although it is unused, some time has passed since it was acquired, and the outer OPP seal has come off. The inner blanket is unopened and brand new.
