About threadless jewelry
Threadless jewelry is a push pin technology. The removeable end (dark grey) has a slightly curved pin. This pin straightens out when inserted into the shaft (light grey). The resulting spring tension force holds the two pieces together securely.
STEP 1 - Insert the pin about halfway into the shaft.
STEP 2 - Bend the pin SLIGHTLY by hand as shown. For a tighter fit bend the pin more. For an easier fit straighten the pin out a little.
STEP 3 - Push in the removable end to close.
STEP 4 - To remove, pull apart both ends. If the jewelry is tight, add a slight twisting motion while you pull out the removable end.
