5L Bin

5L Bin is an engaging binary sequence puzzle from designer Pit Khiam Goh. Known for his work in creating complex sequential mechanisms, 5L Bin results from Pit folding n-ary concepts into a packing puzzle format. The goal is to remove all five pieces and then pack them back into the box.

5L Bin is an extremely well made puzzle. The walnut box is constructed with rounded edges, resulting in a pleasing tactile sensation. The precision-milled aluminum pieces slide smoothly into place with a satisfying click. Once assembled, the contrasting dark wood and bright metal create a visually compelling combination. 5L Bin just begs to be picked up and solved repeatedly.

5L Bin ships in an assembled configuration.

Our work is handcrafted to very precise tolerances and must be kept within the range of 40-60% relative humidity at all times. Failure to do so may cause inoperability or permanent damage.

Handling Metal Puzzles
All metals tarnish over time. Residual oil and salt from handling speed up the process and may leave undesirable fingerprints. Occasional use of our Metal Puzzle Polishing Kit with a coat of Renaissance Wax will keep your metal puzzles in tip-top shape!
