Magical Door Tenyo (2694-w5)

Insert a solid metal key through two plates containing keyholes. Then, lift up a solid metal chain from below the shaft of the key. Despite the fact that there is no easy way to remove the chain, it magically penetrates upward through the key.
Next, you wind the chain around both plates and the key, with a double wrap of the chain. Still, with a simple pull of the chain, you are able to penetrate the key and plates with the greatest of ease.
This is classic Tenyo! Great effect and truly diabolical method. Comes with two plates, metal chain and solid metal key.
