This is an addi circular needle set. I purchased it around 2023-2024, but I have other circular needle sets and haven't used this one much, so I'm offering it to someone who will. There are 8 sizes in total: 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 7.0, and 8.0 mm. There are 3 cords: 60cm, 80cm, and 100cm. This is the long-tip type (the needle part is longer), so you can use it with the same feel as regular straight needles. I checked the cord connection when I purchased it. Thank you for looking.
