Custom NASA Necktie
 
This tie is made of 2500+ aluminum rings and measures approximately 3 inches wide and 21 inches long from the top of the knot to the bottom tip. The knot is set and the piece is actually worn more like a necklace. It attaches in the back with your choice of a simple lobster clasp, drop clasp, or toggle clasp. The neck circumference size is slightly adjustable, as you can hook the clasp to a closer ring than the last one. When selecting neck size, pick the maximum size you want to be able to set it to.
