Based on our mid size coins these “stones” are thicker and have a smooth concave center. Machined from 316 Stainless Steel with near mirror polished finish, and available in 3 configurations:

Regular (no ball) - Both shells have a smooth concaved surface and coin functions as a normal Haptic Coin only.

With Ball - Built with 1 regular shell and 1 pocket shell. The pocket shell is fitted to receive an 8mm ball bearing. The bearing is held in place with the array of magnets. The ball adds an additional silent fidget factor which can be rotated inside the pocket when rubbed with a thumb or finger. You can also attempt to spin the coin like a top on the ball, but with our testing its very wobbly, so don’t buy this expecting a good spinning top experience. Functions has a Haptic Coin perfectly fine with the ball installed or removed.

With Ball Double Hole - This is build with 2 pocket shells and comes with one ball. Remove this ball if you like. This configuration is perfect for DIY customization with colored resins in the ball pocket.
