De Kas is a very challenging ten piece burr puzzle by Alfons Eyckmans. Four eight unit burr pieces interlock with two larger board pieces and four congruent smaller board burr pieces zig-zagging inbetween to make a very unique final shape. The design is in a similar style of Alfons' puzzles we have made in the past, specifically Spiral and Steps. With a level 24.2.2.2.2.2.2.2.4 disassembly alone is a tough task with a few dead ends towards the start.The puzzle was made from a very nicely sourced...

Initially released in 2012, Topless Box is a favorite we never tire of recreating. The solution is tricky and surprising. Upon inspection Topless Box immediately presents a conundrum: with two lids and no top or bottom, how can it be opened? Where do you even begin?The mechanism may be deduced without the use of external tools. No bumping, banging, shaking, spinning, gravity moves, or excessive force is necessary or allowed. Once opened, the elegant mechanism is visible to the solver, and you'll...
