A snug printed case sized for SeedSigner-style builds (Pi Zero form factor) and similarly sized DIY signing devices. Protects the electronics in a bag or drawer — it isn't itself a security feature.
Available in black by default. Check the dimensions below before ordering if you're fitting a device other than a SeedSigner build.
This case is a Behind the Curtain in-house design. If the device inside it is a SeedSigner, that's a separate open-source project — verify its firmware independently, this case has nothing to do with that.
