This memorial keychain can be a meaningful gift to remind one of the precious joy experienced with a child before his or her passing. The keychain disc is pre-engraved with the phrase "forever in my heart" so the saying on the keychain cannot be changed. You can customize this keychain by adding a letter charm and a birthstone charm. Once you've added this item to your cart let me know what letter charm and what birthstone charm you'd like included on the keychain. The circle disc is about 1 inch across.
