Antique Silver Plate Pewter* Magnetic** Toggle Clasp Converter w/ 4 blue crystals. Total length is about 1 7/16". Total width is about 1/2". 

For this magnetic fold over to work, your toggle will need to be at least 8.5mm for inner diameter and no thicker than 3mm. Your bar needs to be at least 12mm long in order to stay inside the loop. We show an example in the pictures. Please see all pictures. Although the length is just under 1 7/16", it will only lengthen your necklace by about 1 1/16" due to where the hole is and where your bar will rest in the loop.
