925 Sterling Silver box chain. This chain is 0.7mm in thickness and 15in in length. Box chains don't tangle, kink, or catch on your hair. Box chains are great for every day wear and because they're 925 Sterling Silver, your skin won't become itchy or green with wear.
925 Sterling Silver can tarnish over time and darken, but this can be remedied with silver cleaner available at any chain grocery store. You can wear your box chain in the shower, but try to avoid chlorine and salt water while wearing your chain. If you do happen to get your chain wet with with chlorine or salt water, make sure to wash it thoroughly with normal water.
Box chains can snap if over time they are yanked on consistently so keep that in mind if you're the type of person who likes to yank and fiddle with your chains! (I'm very guilty of this myself).
