The KOR Delta features striking design and features. Push-button cap allows easy open to reveal KOR's perfect spout, a rounded rim that makes drinking water feel great. The lid also features a lock and protects the spout from dirt and germs when not in use. The cushioned Base protects furniture and prevents slipping on flat surfaces with its soft, rubber base. The convenient flip-top lid that twists off to reveal a larger opening makes cleaning with a bottle brush or filling with water or ice cubes easier. Most bottles force you to drink from an exposed surface, but KOR's covered cap design completely protects the spout from outside germs and particles when not used.
