Kitchen cabinet
Cabinet doors may feature a variety of materials such as wood, metal or glass. Wood may be solid wood ("breadboard" construction) or engineered wood or may be mixed (e.g. engineered wood panel in a solid wood frame)
Shelf (storage)
Shelves are normally made of strong materials such as wood, bamboo or steel, though shelves to hold lighter-weight objects can be made of glass or plastic. DIY shelves can even be made from an old door, colored pencils or books.
