Locus Lock by Boaz Feldman

ocus - a fishy puzzle lock where your wit has to swim in circles to succeed.

Even experienced solvers might find things a little murky as they dive in, unsure which move is the real catch. This trick lock reveals a brand-new mechanism never seen before.

Ready to take the bait?

The goal is to unlock the lock. No hitting, spinning, banging, or using external tools is allowed (or even necessary).

Locus is made of brass and tempered steel, based on a standard lock. 
The package contains the lock, a fabric bag, and an instruction card.
