The seam where the lid lifts is completely invisible, so I spent a solid ten minutes just turning it over before finding the mechanism. Once it clicked open it was such a satisfying little moment that I immediately made my roommate try it.

I handed this to my brother thinking he'd crack it in seconds, but that totally camouflaged opening stumped him for a solid ten minutes. The mechanism is genuinely invisible until you find it, and the click when it finally releases is so satisfying.

The hidden mechanism is genuinely hard to spot, took me a few minutes of turning it over before I found the trick. Only gripe is that it's smaller than I pictured, though the solution is satisfying once it clicks open.
