The collection consists of a range of tops that screw onto reused jars, turning them into containers, jugs, shakers and more.
The set includes adaptations for a sugar pot, milk jug, chocolate sprinkler, oil & vinegar set and a water jug.
Van Ast explains, "By screwing on plastic tops, these readily available jars are turned into vessels with a specific function. A generic jar is transformed into kitchenware, creating more practical and emotional value."
Van Ast originally showed the collection as part of his graduation show at the Royal College of Art in London in 2006.
