These are ABS molds to create your own stack stone or veneer stone. Each mold is individual, sometimes two. You spray them with cooking oil as a release and then pour in your colored mortar as desired. I didn't count them but must be over a hundred. They work well and you can literally save thousand if you're willing to put in the time. Compare to https://www.amazon.com/Drystack-Stackstone-Concrete-Molds-Veneer/dp/B00OYJ1PV6
