This pattern of chainmail is known as 3-in-1 or Half Persian. It has a very neat crossover pattern that looks great with both contrasting colors and as all one color. The majority of the bracelets are made from 18 gauge anodized aluminum, but I also have a few options for other metals including stainless steel and a brass, aluminum, and copper trio. Most of the bracelets will have the option for one color with silver (plain aluminum) as the second color, but a few have more than one color. Pictured I have a 16 gauge aluminum, stainless steel, orange and silver, blue green and silver, and red and ice (a dark shiny grey). I also have a rainbow option which will have the traditional red, orange, yellow, green, blue, and purple on one side and your choice of either black or silver rings on the other. 

These bracelets are very durable, and in the case of the stainless steel one, extremely tough. They are secured with a lobster clasp and are slightly adjustable since you can hook the clasp onto multiple rings, though with this design it can be a little more difficult because of the way the rings lay.
