I found a few fun ones to get you started on creating your own style:
If you’re a Jew or Muslim, or just generally into spirituality, you may like the Hamsa keychain. It brings good luck and gives a Middle-eastern vibe to your outfit.
If you or your kid are into ‘Guardians of the Galaxy’, you may like this Baby Groot Keychain. Groot is a tree-person who transforms into a super hero. Somewhat inspired by Tolkien, no doubt.
If you’re into music, you may want this cool guitar. Available in various colors.
Another fun one, for the photographer who likes it cute, are these camera-keychains. It even makes a ‘chacha’ shutter noise when you press the button.
These are all on the novelty side. I you want something more classic, you may like these tassels handbag rings. Available in all sorts of colors and styles.
Another classic: a (faux) fur pompom ball. For ethical reasons I would stick with the fake fur myself. Stylish and yet a bit spontaneous looking.
