{"type":"firestarter.listing","listing":{"id":"lst_ehQReBOb","product_name":"14 Karat Gold Plated Saxophone Magnetic Eyeglass Holder or Tie Tack","category":"Eyeglass holder","description":"This detailed saxophone is 14 karat gold plated solid brass with a neodymium magnet attached and another separate neodymium magnet. Since it is held on clothing with two strong magnets it won't damage your clothing. Sold as a tie tack or a magnetic eyeglass holder.The tie tack will be without a wire loop (lanyard) or holes.\nTo use the magnetic eyeglass holder just hook your glasses into the hand wrapped wire loop. These work for badge reels and I.D. badges also. The small brass wire lanyard will accommodate up to 13 mm wide glasses and the large up to 15 mm glasses.It is hand wrapped with jewelry pliers, so if you order a larger or smaller lanyard opening I may wrap the wire it a little differently.If you need a larger opening for wider glasses please send millimeter dimensions with order.If you have misplaced your metric ruler, remember that 13 mm=1/2 inch.Need extra magnet backs?
