The skins we mentioned above are not case sensitive – you can enter them in any way you wish, as long as the spelling is correct.
However, not all skins you may have seen in the past are still available. Due to the sensitive nature of some of those skins, these have been pulled by agar.io – for example, you won’t be able to use the Isis skin anymore due to its negative association with terrorist organizations.
