This is a series of gashapon (capsule toys) or trading figures depicting characters or people.
From the Funko website:
MyMojis combine beloved characters with the utility of emojis and the fun of collecting! Each blind-bag vinyl figure depicts a different emotion through the faces of characters from an assortment of popular titles. There are 24 blind bags per display, and each figure comes with a code to download a free digital MyMoji for your phone!
