Using this Alex Woo mini letter charm is super easy. First, pick the letter that means something special to you. Since the chains are sold separately, you'll need to choose a chain that you like and attach the charm to it. Wear it as a necklace to add a personal touch to your outfit. When it comes to maintenance, keep it away from harsh chemicals like perfume or cleaning agents as they could damage the charm. You can clean it gently with a soft cloth every now and then to keep it shiny. And remember, it's a solid, hand - finished piece, so handle it with care to make sure it lasts a long time.
