These are the cords that were used for a commercially available pool bag's drawstring. I believe they are called spindle cords, but I'm not very familiar with handicrafts, so I apologize if I'm mistaken. One cord is approximately 188cm long. The other cord is approximately 140cm long. (I cut off the frayed ends.) The cord thickness is approximately 4mm (to 5mm) in diameter. The color is black. They were used in a drawstring bag and the ends were knotted, so there are marks. I looked for something a little thicker to replace them, but this slightly vinyl-coated type is not very common and I was surprised at how expensive it was, so I'm listing them in case there's a demand... I think they can be used for bags, drawstring pouches, etc. They will be put in a bag and shipped via anonymous delivery in a Yu-Packet Post Mini envelope. Thank you.
