Our Cota Uppercase Initial Necklace can be customized in so many ways, making it a great gift for moms, grandparents and friends. One gift idea for Mom is to stack the discs with an initial for each child. Another idea is an initial of each of your BFFs. Each charm has room for one letter or number, but you can order up to four charms per chain. The charms and chain are available in gold-fill, rose gold-fill or sterling silver.
