Marketed as Himalayan Dog Chews: https://www.amazon.com/dp/B0B1GX8THY/

Despite the initial stick shock on the price, we've found them very effective dog chews, threading the needle on lasting a long time but also retaining interest over time relatively well. Also threading the needle on being designed to come apart safely, yet not instantly disintegrating. In late-stage capitalism part of what you're paying for in that price is that you won't need to buy them very often, if you get the correct hardness level for your dog.
