Aspects® Nectar Guard™ Tips 384

384 Aspects® Nectar Guard™ Tips. For use with Jewel Box, The Gem, HummZinger Ultra, HummZinger Fancy, and HummZinger HighView hummingbird feeders.  HummZinger Nectar Guard tips easily slide onto the feeding ports on the underside of the feeder cover. The flexible membrane in the center of each tip easily opens when hummingbirds insert their beaks to feed and close up tight when the beaks are removed.  HummZinger Nectar Guard tips create a barrier that flying insects can't penetrate.
