There's an app, there's a FOMO "drop" list, there's some larger thing at play here. Can't tell if it's something authentic / art-related, or if someone is just trying to build another brand.
Edit: indeed, this is some new brand / business: "WHO WE ARE MSCHF Product Studio is an internet company. We operate online store(s), create content, communicate with our fans and customers through texts, email and social channel(s), and occasionally promote our products and services both online and offline"
MSCHF (presumably 'mischief') is just another edgy shopify stunt.
