Personalised keychain for a Grandmother - let me know the names for the hearts in the box called 'notes to seller' at checkout. For the hand-stamped elements of these items: Please note that the photos above are just a representation of the product you will receive. I stamp each letter by hand, so there will be small variations in depth, alignment, and space. I feel this adds to the uniqueness of each piece – no two items will ever be exactly the same! Aluminium is a sturdy but lightweight metal. Most of my items are usually under 20g, which is great for keeping your shipping costs low, and for comfort when in use. Your item will arrive in a free organza bag.
