Casse-tête de poche serrure

I bought this for a road trip and those two curved pieces had me stumped for a solid hour. When they finally click into that 3D maze, the satisfaction is real. Perfect little brain teaser that actually fits in my palm.

The two curved pieces fit together in seconds, which honestly made me think it was broken. Turns out the real puzzle is getting them apart again, and that took me way longer than I'd like to admit. Fun little desk toy, just don't expect the assembly stage to last.

The curved edges fit together nicely, but solving the 3D maze felt more about luck than logic. Once I cracked it, there wasn't much incentive to pick it up again — a fun few minutes, but not the lasting challenge I hoped for.
