How to Use This Simulator

1
Set Your Size: Use the top slider to adjust the ring diameter. Watch the ring expand or contract in real-time.
2
Check Knuckle Fit: Increase the "Finger Swell" slider. If the ring turns RED, it indicates a pressure point that might get stuck on your knuckle.
3
Compare Profiles: Toggle between Comfort Fit (rounded interior) and Flat Fit. Notice how Comfort Fit handles swelling better.
4
Simulate Movement: Click "Test Rotation" to see if the ring is loose enough to spin or slip off during daily activity.
