The Super Frozen O'Toro is the tuna belly that is broken down on sight right after harvest and held at -72 degrees Fahrenheit. This is the best and safest way to preserve the freshness and flavor of the beautiful o' toro. With the pristine packaging and infinite time in a super freezer, we at Seas Star can guarantee the o' toro's texture, color, taste and nutritional value will remain intact and ready for consumption!
