Ultra Skulls (Unofficial collection) NFT
This collection of very limited edition nfts is created to make the Ultra project known to as many people as possible. The owners of these nfts will be able to display them as a profile picture on their various social networks so that the image of Ultra can be disseminated. This is not an official Ultra collection, so no utility is attached to these nfts. However, different levels of rarity are assigned to each of the models.
