Query: New Sterling Silver Box Link Chain Necklace 1 MM

Just purchased eight of the necklaces for silver & glass pendants I created in a jewelry class. Three chains are 1MM for the lighter pendants, five are 1.5MM. I mistakenly purchased 16" chains first, then returned them for 18". The necklaces are very high quality as noted in the other reviews. Even the finer chains feel strong and solid. I am very pleased with the purchase and the return for longer chains was easy and prompt. I will definitely buy from these people again. They're gems!
