Can someone tell me what the starbucks gift cards are made of? I had a customer ask if I could engrave his name and number on it. I did and when I hit it with the laser the engraving came out orangish gold color. He was impressed with the results. I am just curious. These cards have holiday scenes on over 3/4 of the card and the far right is clear plastic.
Even in the clear plastic portion of the card came out orange/gold color. I have never had clear plastic/acrylic give any indications of color at all.
Any thoughts?
