These are my black walnuts, which I idly picked up while phone pacing in the parking lot and was then delighted to discover that they make the perfect fidget toy.
They have such great texture, with variation from rough to smooth. I love to run my fingers over it, and rub the walnuts against one another. The texture gives just enough friction.
They are the perfect size and weight to roll around in my hand.
That they are organic is a really important feature. I used to fidget with plastic toys made on a makerbot — the bolt, for example. Their rough edges would leave my fingers sore and raw after a day of fidgeting (I’m an intense person like that, haha….) but the walnuts don’t.
The half walnut with the hole is fun to match up the split edges, and then let it fall apart again, or fit the edge of the whole one into the hole of the other one. the inside is also nice and smooth for tactile variation.
