Plastic sand timer
Most of the plastic sand timers are excellent educational tools for the kids because of the safe plastic frame. 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 have many other designs, and I list them 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.
