FANTOM is a one piece solid cage measuring 47x80 mm made from polished stainless steel.
Rademic released the FANTOM in late 2019 to mark the 50th anniversary of the TV series "The Mystery Of The Puzzle". Following the Foglar's model, this metal hedgehog has 14 sharp spines placed asymmetrically, creating a challenging solution that will not allow you to liberate the hedgehog easily. The puzzle has the only possible solution.
