This appears to be something used when creating hand-drawn stencils for silkscreen printing. It's generally creased due to long-term storage. I can't determine if it's usable, so please check the photos. From the Amazon description: ◆ This is used to create hand-drawn positive films with a matte finish. ◆ Place the rough matte surface (drawing surface) face up on top of the design and draw with opaque ink or an opaque touch pen. ※ Please note that depending on the type of pen, it may not be able to block light. If using Eco-Mercari delivery, I will discount the shipping cost, so please inquire. I have a baby, so my replies may be delayed. I am also selling on other flea market sites, so please forgive me if an item is out of stock.
