The pine 30 minute hourglass measures 9.5" tall. It is made with hand blown glass and is fixed within a hand polished pine wood case. The sand filler is green in color. This item is ideal for keeping track of telephone conversations, meetings and other time sensitive tasks, limited only by ones imagination. This is a very popular gift for corporate events and parties. Hourglasses are aesthetically pleasing ornaments, rather than accurate timepieces. This hourglass is usually accurate to within 5 minutes.
