The gun consists of a blue and pink camo on the handguard, stock, and the magazine, with a "How can I Help?" on the gun itself. The reason why this gun skin came to be is that the mayor of Miami, Florida visited AEXLAB Studio and filmed a cafecito talk on July 15, 2021. To commemorate this event, AEXLAB created and added the Mayor Skin to VAIL VR. Back then, if you want to play with this skin back then from August to November 2021 (??), the skin was only available to Tropical (CEO of AEXLAB). But now in 2022 from the time I'm typing this (2/27/2022), the skin is now available to check out in the Armory from the right of the Cats Statue.
