What looks like a basic bowl set, is loaded with features! The coordinated colored bowls boast both a large, fast pour and small, precision pour spouts. Inside visible measure marks make measuring a cinch. The non-slip base keeps the bowl in place for mixing, while the tilt function makes it easy to set the bowls at an angle to remove every last bit. The bowls are made of durable dishwasher safe poly-propylene and have an anti-glare, scratch resistant soft touch exterior. Each bowl has its own seal tight lid.
