1" XXL sterling silver toggle and bar extender. This toggle is our largest that we now carry. When I order these, I order the same ones every time and they are now fluxuating in size just a bit. This ring can be from 15-17mm ( 5/8" ) round and the bar can be from 24-26mm long ( 1" long). We have used a super strong jump ring on this. This will extend your chain by 1". Please make sure this is approximately the same size as your toggle and bar. I have added the option to add a little bit of 3mm sterling chain in the middle to make this a 1 1/2" long and then for 2" if you want this in longer lengths.
