The Joseph Joseph folding colander is a colander that when unfolded is completely flat, and perfect for storage, but has 12 hinges that lock into place, and when done so, form into a prefectly shaped colander. The folding colander is great for washing fruits and vegetables or draining your pasta, and it won't take up 9/10 of your cupboard space. The folding colander measures 16.53 inches x 12.79 inches x 0.39 inches when laid flat, is made from polypropylene, and is dishwasher safe.
