The whole corn is held inside a cotton liner; heat or chill the warmer as assembled during normal use.Simple, substantial and unmistakably New England.See warming, cooling and care instructions →Care: A Velcro closure gives access to the removable, refillable cotton liner. Heat or chill the item assembled. To wash the outer item, remove the liner; with a smaller opening, empty the corn first so the liner can pass through.
