AS OF 5/26/16...You can order #2AB or #6AB for the back straps...these are the only ones recommended to be sturdy.
***For silver back connectors, We have #35 and #63***
1)*back connectors with tie back (more adjustable when wearing)
2)*back connectors with hook back (less adjustable and can not be worn super tight. must include ribcage measurement)
*We do not suggest wearing connectors tied extremely tight for that is yanking on the jewelry...Simply wear it comfortable and it reduces the strain on the connector prongs. Do not twist Jewelry. Leave flat...
