【Limited sale until October 20th】 I used this until 2 years ago, and it has been stored at home since then. It can be changed into L-shape, round shape, and square shape. As you can see in the photos, it shows signs of use, but it works without any problems. I will ship it in this cardboard box, so please be aware of that. This is a used item, so please only purchase if you understand this.
