This is a set of 5 anime expressions that are made with hair in Vroid and have to be set in Unity after, to be used with your avatars. It's a .vroidcustomitem and has to be imported into Vroid under the "Extra" category. A guide on how to do all of that, can be found here: https://youtu.be/QasZ0BgKJQ0 These are free to use for anything. Just have fun and tell others where you got them from ;)
