Polka dots... 100% polyester. Please refer to the third photo for the size of the dots. They are about the size of a 10-yen coin. Made in China Please consider this item if you understand that it is a home-stored item. Also, please note that there may be some errors due to amateur measurements. There is a possibility that pet hair may be attached, as there was a pet temporarily. Please refrain from purchasing if you are concerned. The product will be folded and packaged, so there may be creases, and some materials are prone to wrinkles, so please be aware of this. Since I own it in a roll, if you have a desired length, please let me know in the comments. I will accommodate as much as possible!
