✅ 1. Recommended Leather Types

（1）Vegetable-Tanned Leather

Характеристики: Naturally tanned, free from harmful chemicals; produces clear, natural engraving results.

Преимущества: Strong color contrast, ideal for deep engraving and dyeing.

Best for: High-end crafts, custom leather goods.

✅Highly recommended!

（2）Chrome-Tanned Leather

Характеристики: Soft, available in various colors, more affordable.

Note: Contains heavy metals and chemicals; may emit toxic fumes when heated.

Recommendation: Use with caution and only with proper ventilation and exhaust systems.

（3）Synthetic Leather (PU or PVC)

Характеристики: Man-made, inexpensive, wide variety.

Risks: Often contains chlorine (especially PVC); laser cutting can release toxic gases (e.g., chlorine) that harm health and damage equipment.

❌Strongly not recommended for laser engraving!
