From 10 Minute Tube Designs comes their SAND SPINNER PIN:
This pin was designed by Caitlin and Matt with help from their good friend Jiggs. It measures 1 1/4″ (base) and the spinner is 1″ with a 2 prong back. As seen in the .gif above, the hourglass is moveable and spins, with a few cutouts so you can see more of the background.
Cost for this pin is $15 + $2 shipping (combined Shipping accepted for multiple orders)
