Hanayama Cast U&U Metal Puzzle

Two U-shaped bolts and four nuts – this looks like a combination of spare parts but looks are deceiving. This puzzle comes with a deviously hidden trick. The key to unlocking these parts is to look carefully at each part first. The theme is complexity. It was designed by Kyoo Wong.
