The artisan series is being discontinued; once these puzzles are gone they will not be remade.
Half Lid Box by the famous Hajime Katsumoto is a similar challenge to Obstacle Box. With only two layers and one slider, you'd think it was easier. You'd be thinking wrong in this case...while there are fewer pieces, the smaller opening necessitates rotational moves which greatly complicate assembly.
Construction of this puzzle is very sturdy with shouldered edges and milled, solid pieces. This puzzle is shipped disassembled.
Admission Restricted -- Fun For The Entire Family!
I love packing puzzles with a restricted opening. Hajime has created an elegant design, and Eric has crafted a wonderful puzzle. This is the type of puzzle to leave on the coffee table.
Tricky and fun
A very well-designed and beautifully made puzzle - tricky and challenging, but not impossibly difficult. Lots of replay value and a great gift.
Half-lid is another beautifully crafted puzzle with a tricky non-intuitive but readily reached solution; possibly a tad easier than 4-L but just as satisfying; the moveable half lid is a genius twist; tolerances on the puzzle are perfect.
