UPC Code: The majority of Grenco Science products will have a bar code with a UPC Code on the back. If the box in which your product came in doesn’t have this, please call the Customer Service line to discuss the authenticity of the purchase.
Pen(s) wrapped inside of the box: If you notice that the pen(s) are wrapped individually in cellophane INSIDE of the box, then the product is probably inauthentic.
LED light: Unless you have an Artist or Charity Series product that displays a different LED light than the standard blue (for example: the Huf Original microG has a green LED light and the Claw Money Original microG has a pink LED light) the product is counterfeit.
