Our puzzles are made from 3mm nickel plated wire giving it a smooth and polished look. With The Rack, your task is to simply remove the string from the wire frame without detach the beads. As a difficulty rating of 8/10, you’ll find its solution more complex than its design appears to be. The Rack is from our wide selection of Puzzle Master Wire Puzzles and comes in a convenient clam shell packaging, perfect for storage.
