This is a bag-in-bag made of felt material. It has a thick, sturdy fabric and stands on its own. I bought it, but I'm using a different color, so I ended up not using this one. It makes it easy to organize the inside of a tote bag, and I like using it. I took it out of the plastic bag, but it's unused. It measures 23cm wide x 15cm high x 9.5cm deep.
