Nest is a collection of practical, space-saving mixing, measuring, and prep set. Their innovative design allows the individual pieces to be nested together, occupying minimal space. There are 3 different sized sets available: the 9-piece, 8-piece, and 7-piece. The mixing bowls have non-slip bases and easy carry handles. The small mixing bowl includes measurements inside for added convenience (milliliters and fluid ounces), and a spout for accurate pouring. The measuring cups 'snap' together securely. Not for use in microwave. All pieces except for steel sieve are dishwasher-safe. Sieve should be hand-washed.
