Bioten is a brand for women who are nice, gentle and sensitive. Activities around Christmas are to make fans happy and spread joy all around. 
Entering the application, the users see various designs of Christmas cards. Then they need to make their choice and write a personal wish to the friends they want to greet for the coming holidays. This is how we want to spread the magic of Christmas. For those users, who are less creative or have less time to think about the personal wishes, there is a choice of ready-made ones.
