This sand timer is one of the giant sand timers in our factory, and it is not the largest one. The size of the sand timer is Dia 120*430mm. With this size, the running time can be 2 hours. The sand inside the bulbs can be in different colors. And there are hundreds of colors of the sand that you can choose. As the hourglass is of large size, so it is a little difficult to make, and we can do it.
I try to take more images of it and show them to the clients, and I shoot it from different directions. When I check the images, they are all the same. So I select the only images and make this page. If you want to check more sand timers, please can check the hourglass page.
