# Skins The physical attributes of koins can be very unique, but they are beyond our control. However, we have the possibility to customize its appearance to our liking through skins! These are NFT assets you can acquire to equip your koin and thus give it a unique look. Of course this change isn’t permanent, you can unequip it to return your koin's appearance to normal. You can also sell the skins to other players! ![](/files/TkjvLu2JwB16AyyF2seH) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
