Bandai opens preorders on September 17 at 16:00 for the S.A.M. Cocoon, the item Firefly uses to transform in Honkai: Star Rail. The prop has a wing deployment gimmick, light effects in four modes matching SAM's transformation states, and recorded lines from Firefly and SAM plus battle skill voice lines and BGM. It costs 22,000 yen tax included, orders close October 18, shipping is set for May 2027.
The S.A.M. Cocoon ships with a display stand and replacement parts so it can be posed with the wings deployed, matching how the item looks in the game. A rechargeable battery charged through a Type-C terminal powers the light effects and the wing mechanism, which opens both wings when the button is pressed.
The set includes the main unit, two display parts, one stand, two small and two large wing effect parts. The order window closes October 18 at 23:00, and shipping is scheduled for May 2027.
