How to resize IonTopia expanding bracelet
There is no need for a resizing tool to remove links from an expanding bracelet.
To expose the internal parts that holds the links together, pull it to two sides.
While keeping the bracelet stretched, press with your thumb on one of the links as in the picture, to keep it open.
You can see now how the links connected, with a hook style on one side, and a bar on the other side. Now remove the hook from the bar.
Now that the bracelet is open, repeat the process to remove links, and reconnect the two edges the same way.
