What determines the price

  • Rarity of morph, complexity of combo.

    High

    Ball python morphs are diverse, and the combination of combo morphs determines rarity. Rare morphs such as Pied Ball and Crown are especially highly valued.

  • Strength of morph expression, contrast.

    High

    The contrast and clarity of body coloration and pattern indicate the completeness of the morph. The stronger the expression, the higher the evaluation.

  • Health condition (body structure, skin, eyes).

    High

    The body should have appropriate thickness and length with visible muscle tone. Clear eyes, no incomplete sheds, and no abnormalities around the mouth are basic points to verify.

  • Feeding history, feeding status.

    Medium

    Whether feeding on frozen mice and similar foods is stable. Individuals with frequent feeding refusal may be difficult to handle.

Appraisal points
