Single-layer polyester. Stored at home, so there may be some creases. Please refrain from purchasing if you are sensitive to dust, stains, the smell of mothballs or chests of drawers, or cat hair. If you have any problems, please contact me before leaving a review. Will be shipped in a simple package without a box. Please note that there may be creases during shipping. If you live in an area where separate shipping fees apply, such as remote islands, please contact me in advance.
