This new fount is practically unbreakable. The jar is now ribbed for extra strength as pictured. It is injection molded instead of blow molded for a much smoother inside with no turned-in bottom lip to hold back water and have a buildup of unfriendly bacteria. The red base attracts birds so they will drink more. The jar has a 7" mouth that is easy to twist, the base locks and twists instantly. The jar and base are nestable for minimum space in shipping and storage.
