The classified Prototype Mk. ∞ is Fidget Vault's most advanced unreleased product to date. Unfortunately, due to legal concerns, temporal instability, and several strongly worded emails from the Department of Physics, we are unable to reveal what it actually does.

Machined from a proprietary blend of unobtainium, hopes, dreams, and at least three recycled shopping carts, the Prototype Mk. ∞ features an industry-leading 0 to 47 feedback points depending entirely on how much coffee you've had that day.

The internal mechanism utilizes a quantum-assisted reverse-hybrid bearing system that simultaneously spins, doesn't spin, and is still being debated by leading scientists.

During testing, users reported:

Increased happiness
Decreased productivity
An overwhelming urge to buy more fidgets
Mild confusion regarding the laws of space and time

The Prototype Mk. ∞ supports clicking, sliding, spinning, rotating, contemplating, and in rare cases, achieving enlightenment.
