The ISO - Silent Magnetic Haptic Coin (Richlite)

From Our Shop to Your Pocket

We're a small two-man shop in Charlotte, NC, and we design premium fidgets. The ISO is the one we've wanted to build since day one: a haptic coin you can run through your fingers all day without making a single sound. 

This one we make in house. We've got the machines here in Charlotte, so we cut these ourselves in small batches, usually a couple dozen at a time between slider and prybar runs. Steve finishes and assembles every single one by hand. It takes a lot longer than ordering a production run, and yeah, that shows up in the price. Worth it, in our opinion.

The ISO

The ISO is a silent haptic coin: two precision-machined halves that rotate around each other on a high-quality and long-lasting bearing, indexing into position with a firm, satisfying pull from permanent neodymium magnets you feel instead of hear. No bearings clicking. No detent ball snapping. No noise for the room around you to notice.

What sets the ISO apart is the profile. The top surface and outer edge carries machined finger grooves that sit naturally where your thumb and index finger land, giving you grip when you're spinning it and a smooth, contoured surface when you're just holding it. It works as a magnetic fidget coin and as a worry stone, which is exactly how most people end up carrying it.

Why We Built It

Most fidgets ask you to pick a moment. Clicky sliders and fidgets are great at your desk but can be a problem in a meeting, a lecture, a waiting room, or anywhere with a microphone open and people nearby.

We wanted something with no wrong moment. Powerful neodymium magnets gave us that. They deliver real, mechanical resistance and a clean index at each position, but they make the feedback happen through your fingers rather than audibly through the air. The result is a fidget that gives you the same feel than a clicker or slider but none of the sound.

Silent by Design

Silence isn't a side effect here, it's the design brief. Every internal surface, magnet pocket, and tolerance was chosen to keep the motion smooth and damped. You get the rhythm and resistance your hands are looking for without pulling anyone's attention toward you.

Frequently Asked Questions

Is the ISO actually silent?
Yes. There's no bearing ramp and no spring detent, which are the two parts that make most fidgets audible. The magnets index the halves without any click or snap, so you can use it in meetings, classrooms, offices, and shared spaces without drawing attention.

What are the finger grooves for?
Grip and comfort. They give your thumb and finger a defined place to sit while you rotate the coin, and they turn the ISO into a worry stone when you're just holding it rather than actively fidgeting.

Why is this ISO more expensive than metal ones?
Because we make it ourselves. The metal ISOs are produced in large runs, which drops
the cost per unit. The ISO is machined, finished, and assembled by hand here in
Charlotte in small batches. Material cost is the smallest part of what goes into one
of these.

Can I take it apart?
No. The ISO is built to be silent, solid, and last a lifetime. We designed it with sealed bearings to ensure dirt and grime cannot damage the bearing internals. 

Will the magnets weaken over time?
Under normal carry and use, no. Neodymium magnets hold their strength for decades barring extreme heat or physical damage.

Is the ISO covered by a warranty?
Yes. The ISO is covered by our Limited Lifetime Warranty.
