Solid, quality sterling silver chain! Sterling silver can be polished over and over to bring back its shininess and will last a life time. [ WHAT LENGTH SHOULD I CHOOSE? ] • Please refer to the length guide photo for a general guideline. The most accurate way is to wrap a string, phone cable, etc. around your neck, and find the comfortable length. Then, measure that with a ruler or tape measure. • The lengths we offer are from end to end, including the clasp and chain tag. • Please contact us for custom lengths. [ SIZE & MATERIALS ] • All components are solid .925 sterling silver. • Closure: spring clasp or lobster clasp. • The chain tag is about 3.3mm wide. If the inside diameter of the bail of your charm is larger than 3.5mm, it should go through our chain. • Chain link size: Dainty: about 1.2 x 1.5mm Fine: about 2 x 2.4mm Medium: about 2.5 x 3.2mm Figure 8: about 2.8x3.6mm [ NOTES ] • Each order will be nicely packaged and include no pricing information (except for international orders for which the item value must be declared on the customs form). • We insure each shipment and offer a 30-day warranty.
