This is an eco-bag from NHK Studio Park. I believe it was sold about 20 years ago. The approximate measurements are: height 40cm, width 30cm, depth 11cm. It has an inner pocket, and you can store the bag itself in that pocket when not in use (see image 2). The size when stored is about 18cm x 15cm. I carried it around in its compact state, but I never actually used it. The overall condition is good.
