Outfitted with grey lids—a Crate and Barrel exclusive—these two glass bowls provide a secure seal to keep food fresh in the fridge or on the go. Use the larger bowl to mix cake batter and the smaller to whip buttercream; the lids will keep your cake components fresh until you're ready to use them. Or make two crowd-pleasing salads in the bowls, seal with lids and transport to a potluck, picnic or holiday feast. The bowls also store leftovers securely in the freezer, reheating them easily in the microwave or oven. This set includes 2.5- and 4-quart bowls with lids.
