This Tarsk, upper arm box, is crafted from fine steal. Set with a one way opening at the top for that of Tarsk of copper or silver to be placed within. The spring within does snap closed, thus ensure no coin can escape. The dual cuffs are made of hardened steal, with a hollow inner locking mechanism for which can only be released through the special locking mechanism at the bottom of the box itself. When the key is inserted and twisted the first time, it will unlock the arm bands, the second twist will unlock the bottom of the box and allow the coins to be collected. Any attempt to remove the bands, with force, from the 's arm, without the key, will cause the cuffs to tighten down, thus cutting off the circulation unto her arm.
