At the heart of the product lineup is the Official HYTE Y70 Firefly Case, which features a titanium silver colorway, 360-degree character artwork, and thematic elements and iconography inspired by Firefly and her S.A.M. armor throughout the chassis. In addition to the standard case, there are still limited-edition JP versions of the case that feature Kanji / Katakana branding for the Honkai: Star Rail logo. There is also an exclusive keychain based off Firefly's in-game phone case that can only be obtained by ordering either the US or JP PC case.
