This is a short-type sync cord from Sunstar Strobe. It's spiral and about 40cm in actual length. Perfect for connecting to radio slaves. It's a phone jack, so it can also be used with other companies' monolight strobes, such as Comet strobes. If anyone is looking for a practical item, how about this? Shipping will be via Yu-Packet Post Mini. Instant purchase is OK. Shipping costs will be covered by me. Price negotiations are not accepted. Thank you for a smooth transaction. twinkle monolight strobe large strobe COMET strobe
