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 dishes. Each bowl is made from 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 each other, taking up minimal space. The bowls come with interlocking lids and non-slip bases. The largest bowl in the set also has a convenient measuring guide 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 in the top rack of the dishwasher.
