These are our Thin Blue Line Bracelets that are made with true spec 550 paracord. The centerpiece is made of glass with the image built into the glass. We would suggest measuring your wrist before ordering to make sure it will fit before placing an order. You would measure your wrist and add one inch to allow for a comfortable fit. You can return the bracelet for a full refund by shipping it back to our offices if you’re not satisfied for any reason. These bracelets are size 8. We’ve found the size 8 to be one of the most popular sizes, which is the reason this is the only size we carry for this bracelet.
