Laser Engraving Machine Used

This was bought as a gift for me to use in my crafting and has only been used once to give me a tutorial but it is of no interest to my line of crafting hence the reason for selling it. I cannot give any information about it as I have no interest in it except it connects to the computer. It comes with wood coasters and the instruction book that came with it. I will try to answer any questions about it but cannot help with how it works as I don’t know I only know it wasn’t a cheap gift.
