ParaWire's exclusive coloring process produces the brightest colors with the most resilient finish.  Metallic colors are 99% pure copper wire with ParaWire’s exclusive non tarnish coating.  Silver plated colors have the same copper core as metallic wires, but are then plated with 99% pure fine silver before the final color is applied.

ParaWire has the most durable coating on the market and will withstand plenty of general wear and manipulation. Please keep in mind that extended periods of direct sunlight and/or water/humidity exposure may weaken the coating and/or cause it to become faded/discolored. Be gentle and kind to your wire and it will stay beautiful for many years to come!
