The Nest 100 Prep&Store by Joseph Joseph is a 4-piece bowl set with lids. The bowls are ideal for preparing and storing food and meals. Each bowl is made of high-quality stainless steel and features a silicone lid. The Nest series includes practical, space-saving kitchenware with a unique range of sets for preparing, storing, and cooking food. The innovative design allows the individual elements of Prep&Store to be stacked inside one another, taking up minimal space. The bowls come with interlocking lids and have non-slip bases. The largest bowl in the set also includes a convenient measurement marking on the inside. After use, the bowls can be easily cleaned in the dishwasher. The lids are also dishwasher safe but should only be cleaned on the top rack of the dishwasher.
