Most plastic sand timers are excellent educational tools for the kids. The safety issues of kids’ products can’t be overemphasized. The plastic caps and tubes protect the hourglass inside. Typically, the hourglass won’t break. But even it’s broken, the breaking glass will be kept inside, and not hurt the kids. There are drop tests before export.
I am trying to list all of the plastic sand timers that we have. So the customers who are looking for these hourglasses can have a one-stop experience. We are a sand timer manufacturer, so there are many other designs, I’ll list them all on the hourglass page. There is a plastic injection department in our factory, and this is an advantage to help customers to develop new items.
