This is a compact-sized stretched canvas. I purchased it at Tokyu Hands for my first art project. I bought two, but I'm selling one because I didn't use it. It's compatible with various art materials such as acrylic paints, watercolors, and oil paints. Size: 18cm x 14cm (F0) Thickness: Approximately 1.5cm The Nasuno Gazai Kogyo Paulownia wood frame uses a laminated paulownia material, which is also used in furniture. This makes it stronger than conventional paulownia wood frames, reducing slack in the tacks and warping of the wood. It's a lightweight, warp-resistant, and reasonably priced ECO product.
