Okay, no they are not made of silver but they do look it! In fact they are coated with Zinc which means they're light in colour and don't shed the grey dust that many spiral bones do. This means they're a great option for use in wedding dresses because you won't see the shaded lines where the bones rest below the fabric and your fabric and hands won't get dirty when you insert them. These bones are currently only available in 10mm or approximately 3/8" wide and in a small selection of lengths.
They're wider than some spiral bones, and stronger so they offer more support but they are still flexible for comfort and to enhance curves on those voluptuous women whose experience has been that spirals don't work. These NEW bones are worth checking out at www.farthingales.on.ca
