The chain can be shortened if you prefer, and the extra links will be included in the package in case you ever need them. Just specify the length you need in the "Message to the Seller" box as you check out. Remember, if you save the bits, Silver Apples does repairs for free if anything should ever break your Silver Apples jewelry. All you'll pay for is shipping it back to Silver Apples.
