This is an eco-bag that came as a supplement to the magazine PEAKS. It's unused, but please be aware that there may be minor stains from storage. I can't remember which issue it was from, but I've had it stored away. I think it was probably 2 or 3 years ago, but I'm not sure. It's made of very lightweight, white Tyvek fabric that feels nice to the touch. It has creases from being stored for a long time, but they should disappear with use. It seems convenient as an eco-bag for everyday use that doesn't take up much space. Please refer to the photos for the size, as I've placed a ruler on them. For shipping, I will fold it in four or less and pack it compactly, so please understand. Thank you very much.
