【CSD】 x Warner Bros. 【Harry Potter】 launching IP face mask through crossover collaboration.

CSD collaborated with Warner Bros. twice in 2021. The second face mask series consisted of themes in the four Houses, namely Gryffindor, Ravenclaw, Hufflepuff, and Slytherin.
Each face mask of the house uses the name and elements of the house such as the representing animal. The face masks are incorporated with ear loops printed with dual colors responding to the signature color of the house. The lower-left corner is embossed with the special seal of each house.
