마틴스 메나스 대형 | 스튜어트 코핀 #217 나무 퍼즐

I've spent hours trying to solve these four interlocking pieces, and the fit is so precisely cut that once they click together, there's barely a seam. It’s a satisfying challenge that really makes you think, like a mental workout.

I expected a quick solve and instead lost most of an evening to this thing — the four pieces look like they should slide together instantly, but the fit is deceptively tricky. The wood has a nice weight and the joints are cut clean enough that it never feels loose or cheap.

The four mahogany pieces look simple until you actually try to fit them into a cube. Took me three evenings and a lot of failed attempts before it finally clicked, which is exactly what I wanted from a Stewart Coffin design. Worth every penny if you like puzzles that genuinely fight back.
