No/No Feeders have all metal construction No wood and No plastic. The durable squirrel damage resistant construction will last for years and years. The simple wire mesh design helps to protect birds from avian diseases while accommodating both clinging and perching birds at the same time. No cleaning is needed, but it is dishwasher safe if you insist! The unique design allows the feeder to ship and store flat while no assembly is needed each feeder is ready to hang and fill. This feeder holds over 2.5 pounds of black oil sunflower seeds. The huge feeding area which feeds 15 or more birds at once, means fewer refills. Makes a great no hassel gift idea for friends and family.
