Support connectors (19 x 12.5mm) are compatible with 10mm round cabochons. You will find some in my shop in the "cabochons and supports" section.

Also for earrings, long necklaces, bag jewelry, key rings,... - If you buy more than one item, don't forget to tell me ask for the total BEFORE paying by ebay messaging or email, because the reduction in shipping costs does not happen automatically, and ebay shopping cart not working well. Items are carefully packaged in bags, bubble wrap if necessary, and taped in the envelope. Every order is important, small or large. My dear customers from Europe and around the world, if you want a tracked shipment, please ask me by email, I.
