Geekshare is known for their really cute (and quality, imo) Nintendo Switch accessories and honestly, I’m surprised it took them this long to officially partner with Sanrio to release some adorable accessories.
As shown on one of their official Taobao storefronts, Geekshare has an upcoming collaboration with Sanrio in the works, where they’ll be releasing several docked Switch covers and thumb grips themed after Kuromi, My Melody, Cinnamoroll, and Pochacco. Pochacco won't be getting a cover.
Geekshare usually makes their products available on their official website or their Amazon storefront some time after they’ve been released in the Chinese market, so I’d also expect these to be released sometime for international Sanrio-loving Switch-havers.
Then again, licensing for Sanrio products can be a bit weird abroad, so I have no guarantees—but I’ll keep you posted if/when they’re available for everyone outside of China to purchase. ◡̈
Update (June 30th, 2023): ...there's more!
Geekshare has also made previews of other products in this collection available: game cartridge cases, cases, a Kuromi screen protector, and skins.
