I purchased this roll of canvas about 20 years ago from an art supply store in Shinjuku. It has been stored rolled up and used as such, and I rewound it to measure the length. It is 115cm wide with selvedges and 496cm long. It is 100% linen. I believe it was made by Funaoka, a Japanese manufacturer. You can use it as is, or apply gesso to your preferred thickness for oil or acrylic painting. I'm not very familiar with canvas grades, but it seems to be a medium or medium-coarse weave. Please check the images for confirmation. If you have any requests, I can provide photos comparing it to something else. I think it's a good, sturdy fabric with a tight weave. The wrinkles on the edges will disappear when stretched on a wooden frame. There may be some loose threads. There are stains on the selvedges, as shown in photos 6 and 7. There are occasional knots where the thread is slightly bunched up, as shown in photo 5. The photos also include images of similar fabric from the same roll. I am open to a small price reduction.
