Lumbar Vertebrae Model - 4-Stage Change Model (L4/L5) - Chiropractic, Osteopathy, Medical Education Material

This is a comparative model showing the age-related changes in the lumbar spine (L4/L5) in four stages.
It is a standard teaching material used in medical settings, chiropractic clinics, osteopathic practices, and chiropractic offices to explain disc degeneration and bone deformities.

[Important: Product Condition]
Sticky: There is overall deterioration due to age.

Cleaning Status: After washing with dish soap, the item was wiped clean with alkaline electrolyzed water and ethanol. However, due to material degradation (hydrolysis), the stickiness could not be completely removed.
