Tension Rods Quantity: 8 Size: Approximately 18cm (shortest) to 27cm (longest) Thank you for viewing. These were purchased from Seria or Daiso. They were used for about a year. Since they were installed between boards, the parts that were in contact with the boards have some discoloration. Other than that, there are no noticeable stains. Please check the photos. When in use, they supported items weighing less than 1kg with two rods. The tension rod function has also been confirmed. I am selling them because I no longer need them.
