Good to Know

• Clean the processing surface before engraving. Before processing, clean the rectangular top surface (processing surface) with alcohol to ensure optimal UV inner engraving quality.
• Learn UV Inner Engraving. Click here for the UV inner engraving tutorial. 
• Handle with care. K9 crystal is durable but may chip or crack if dropped or subjected to strong impact.
  
• More about K9 crystal. K9 is purer than regular soda-lime glass — no green tint, virtually no bubbles — which is what lets it hold a clean internal engraving. See Regular Glass vs. K5 vs. K9 Crystal.
