This is a Rectangle Impossible Passthrough Fidget designed to create a smooth, satisfying sliding illusion.

At first glance, it looks like the inner rectangular piece shouldn’t be able to pass through the outer frame… but it does. The precision tolerances allow it to glide cleanly while maintaining the “impossible” effect.

🔹 Features:

• Clean rectangular geometry
• Smooth passthrough motion
• Tight, satisfying tolerances
• Minimal, modern design
• Great desk fidget

The rectangular shape gives it a different feel compared to circular or spherical passthrough designs. The straight edges make the movement feel controlled and mechanical — almost like a precision puzzle.
