When sourcing pink handbags, the material choice directly impacts the product's lifespan and perceived value. For Genuine Leather, ensure it is Top-Grain or Full-Grain for premium markets, as these offer the best durability. For PU or Vegan Leather, verify the thickness (ideally 1.0mm+) and check for scratch resistance. Pay close attention to the colorfastness to rubbing (ISO 105-X12); pink pigments can sometimes fade or transfer if not properly treated. Additionally, inspect the edge paint (oil edge) for smoothness and ensure it does not crack when flexed.
