Yes, there are folding shopping bags. Some of them are even available here at Japan Trend Shop. But haven't you ever wished for a bag that could function as a regular bag for your laptop and school or work documents, and that can easily become a tote big enough to accommodate, say, 34 liters worth of groceries? This is exactly what the Warp Expandable Shopping Bag is.
When it's closed, the Warp Expandable Shopping Bag is a stylish 33 x 39 x 1.5 cm (12.9 x 15.3 x 0.6") briefcase with two compartments and two inside pockets, plus an outside pocket. But unzip it and the capacity goes up 17 times, allowing you to pack all your groceries together with everything else that was already there before you went shopping! Available in khaki, brown, and black, the bag is fully washable, so you can use it again and again for years to come.
