Rebel Crate was founded on the premise that a pistol case should have everything you need to take to the range. The founder was annoyed at not having dedicated places for things like safety glasses, extra magazines, a suppressor, a box of ammo, or ear plugs. When you first purchase a pistol, it typically comes with things like a cap for the threaded barrel, a threaded adapter, different grips, specialized tools for adjustment, and other various parts. There's never a good place to store these items.
Scouring the internet, nothing was available. After 3D printing many prototypes, the final design was ready for injection molding and launched in 2025. To continue iterating and improving, things like an altitude vent, better water proofing, a wider selection of colors, and satisfying mechanisms to interact with are all on the roadmap.
