This is a method for assembling a dual inner flexible insulated pouch. The filaments are preferably extruded polymeric filaments and have depressions formed therein providing transverse drainage paths across the filaments. The body member externally houses a clamp means, a toggle switch, a fastening means, and two opposable ends with threads for receiving the head and tail members so as to provide a unified device. The individual barcodes can be combined into a composite barcode, which can have patterns and modules used can include many different sizes, shapes, colors and locations of such patterns and modules within the barcode. In one or more embodiments, the concentration of platinum is less than 50 atomic percent, andor the concentration of chromium is less than 30 atomic percent, andor the concentration of copper, nickel, or a combination thereof is at least 35 atomic percent.
