Decanter of Endless Water
This item looks like an ordinary glass flask full of water. The stopper can't be removed unless you speak one of the item's three command words, each of which causes water to pour forth in a different way. Pulling the stopper straight out creates fresh water, and rotating it as you pull creates salt water. Any effect of the decanter lasts until the decanter is plugged (with its own stopper, a finger, or the like).

Traits
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
Effects with the water trait either manipulate or conjure water. Those that manipulate water have no effect in an area without water. Creatures with this trait consist primarily of water or have a connection to magical water.
