These remarkable "brown paper bags" are stitched from ingenious Japanese Naoron paper in a 150 year old factory in the shadow of Mt. Fuji. A blend of washi and wood pulp reinforced with synthetic fibers spun from recycled plastic bottles, this "paper" is soft and sturdy, supple and sustainable, hard to tear and water resistant. The resulting foldable storage "bags" are a streamlined workhorse dream for elevated corralling. Or, you could use them to pack your lunch every day for a thousand years. 3 1/2" x 3 1/2" x 4 3/4"
