## About this gift

Turning 21 calls for a 21st birthday necklace that does the talking: a key charm on a sterling silver chain, with a card to match. It suits a girl's 21st whether she is a best friend, a daughter or a niece, and the card already carries the message.

Choose 16 inch or 18 inch for the chain, which is sterling silver either way. The 15 mm key charm in Tibetan silver has an antique finish. The card reads Happy 21st Birthday, have a wonderful day, with space for a short note or can be left blank. The whole gift fits through a standard size letter box.

Twenty-one is a milestone worth celebrating, and it deserves a card that says so. Give it on the birthday itself, or in the days around it. Pick 16 inch or 18 inch and mark her 21st birthday in style.
