The magnet (concealed in the shaft) pulls the top down into the shaft with its magnetic force. This action eliminates any rattles which are sometimes found in other spinning top shafts. Shafts are 2ba thread size and are sold in sets of three. Available in medium and short lengths and these colors: black and silver.
