Bandai opened pre-orders for the Honkai: Star Rail S.A.M. Cocoon on September 17 at 4:00 PM on Premium Bandai. The item is the transformation device Firefly uses to become SAM in the HoYoverse game. It is priced at 22,000 yen including tax, with the order window running until October 18 at 11:00 PM. Shipping is scheduled for May 2027. The product includes a sculpted main body, large clear wing parts, and a light-up feature with four modes that reproduce SAM's four transformation states. Operating the buttons deploys both wings. It also plays lines from Firefly and SAM, battle skill sound effects, and BGM. A dedicated display stand and replacement parts for the deployed wings are included, so the item can be displayed wings-open. Power comes from a rechargeable battery with a Type-C port. The set ships with two display parts, two small wing effect parts, and two large wing effect parts.
The run is aimed at buyers 15 and up. Bandai lists the wings-stored measurements as roughly 105mm long, 248mm wide and 78mm tall. With the wings deployed those figures change to about 440mm long, 183mm wide and 50mm tall.
The listing carries several conditions. Orders close once the planned quantity is reached, and if demand runs high Bandai says the planned quantity may be adjusted and the product may be sold again. Shipping timing may shift slightly depending on order status, and the posted photos and specifications come from development, so they may change without notice. The images show a prototype, so colors and finish may differ from the final item, and everything outside the set contents is sold separately. Bandai notes the product may also be sold outside Japan and at stores or events.
Inside frames the device as the transformation item Firefly uses to become SAM, matching the phrasing Bandai used in its own product copy.
