Please note, this listing is for two Tiny Initials on one chain. This adorable necklace makes a great personalized gift! The sandblasted sterling charms are stamped with an itty-bitty letter and come with a lovely, 18" super-fine, sterling cable chain. The circle component of the charms is ~9mm (the model photo is of a single charm). Please include your choice of letters during checkout.See my other Tiny Initial Necklace options (one, three, or four charms on a chain) also listed in my shop. These are also available in 14k gold vermeil.
