Standing at 11.75″ in height, and with a diameter of 4″ at the widest points, this glass sand timer will run for an hour, as long as all the sand is at one end before it’s flipped over. The hourglass was designed in a triple globe style, with the two end globes being separated by a smaller one. The golden colored sand flows from the top globe down through the middle, to the one at the bottom. At times, it will accumulate in the central globe, though this is not a problem, as it should still be flowing downwards.
