This is a suspension holder for NEUMANN condenser microphones, specifically the U87Ai and TLM67. The string is also included, but it is completely stretched out, so please consider it as a bonus. I believe it is a genuine product as it was an accessory for a U87ai I purchased on a flea market site a few years ago, but I'm not certain. Please consider this only if you are looking for a genuine product and can distinguish between genuine and third-party products. I believe this is quite cheap considering it's a used genuine product.
