Durable stainless steel construction and leakproof, snap-on lids make these mixing bowls a lifesaver for potlucks, parties and everyday prep. There’s no need for plastic wrap: Just mix up a batch of guac, pasta salad or marinated meat, then pop on the matching lid and snap the tabs into place. Whether you’re putting chicken wings in the fridge to marinate or taking French onion dip to a party, you get a secure seal and a flat, stackable surface, without resorting to single-use plastic. (The biggest bowl even has a lid with a handle so you can carry it to your destination like a tote bag.) The whole set is dishwasher-safe: The bowls are made from sturdy 304 stainless steel and the lids have crack-resistant and shatterproof plastic. When not in use, simply nest the bowls with the lids on and cover with the largest lid.
