Entropyseal Safe Box: Tamper-evident container with pearl seal

During the Cold War, agents allegedly placed a hair across their hotel room door before leaving. If it was still there in the evening, nobody had been inside. A neat trick, but unfortunately impractical for hard drives, hardware wallets, or that backup key for the data center.The Entropyseal Safe Box from Switzerland solves the same problem with pure randomness. Inside the transparent lid lie countless black and white pearls. When you close it, they mix into a pattern that will never occur the same way twice—essentially a fingerprint made of entropy. You capture it with your phone. If the container is opened, the pearls rearrange themselves, and the original pattern is lost forever. Comparing it with your photo immediately shows whether someone has tampered with it. A free companion app stores and compares the fingerprints for you, or you can do it by eye if needed. Since nothing gets torn or broken, the box can be reused as many times as you want.Made for admins, crypto enthusiasts, and everyone who prefers to trust their backups when they can verify them. Trust is good, entropy is better.
