About the Product
A disentanglement puzzle is a type of mechanical puzzle that involves disentangling one piece or set of pieces from another piece or set of pieces. The reverse problem of reassembling the puzzle can be as hard as-or even harder than-disentanglement. There are several different kinds of disentanglement puzzles, though a single puzzle may incorporate several of these features.

Plate-and-ring puzzles
A plate-and-ring puzzle usually consists of three pieces:
*one plate or similar displaying many holes and/or indentations
*a closed or nearly closed ring or a similar item.

Wire puzzles
Wire puzzles consist of two or more entangled pieces of more or less stiff wire. The pieces may or may not be closed loops. The closed pieces might be simple rings or have more complex shapes. Normally the puzzle must be solved by disentangling the two pieces without bending or cutting the wires. Early wire puzzles were made from horseshoes and similar material.

Wire-and-string puzzles
Wire-and-string puzzles usually consist of:
*one piece of string, ribbon or similar, which may form a closed loop or which may have other pieces like balls fixed to its end.
