Using these boba milk tea key charms is super easy. You can attach them to your bag's zipper, your backpack straps, or your key sets with the provided key ring and clip. If you want, you can also use them as a cute toy figurine to decorate your desk. When it comes to maintenance, just keep them away from sharp objects to avoid scratches. If they get dirty, you can gently wipe them with a soft, dry cloth. Don't expose them to extreme heat or cold, as this may damage the charm's color and shape. Have fun showing off your unique charm!
