I entered the site once, but I'm selling it because I have extras. It's unopened, unused, and brand new. There are some minor scratches due to warehouse storage. *One box is crushed. One set costs 10,000 yen at Monotaro and 6,396 yen on Amazon. This is a cable connector from 3M Japan. It can connect one each of CV 38sq, 60sq, and 100sq cables. I have some extras of different sizes, so I'm hoping someone will take them. The manufacturing date is April 2023, so I'm selling them at a bargain price. I will ship it either on the same day or the next day.
