At that time, there was a lot of laser engraving that saw this brand in the purchase. I also listened to the staff’s introduction to this laser engraving in the past. I will know what the product is good, but I didn’t listen to the moment I was interested in the laser engraving in their store, and when the staff gave me the trial, I bought it immediately. No one could make the laser engraving function too powerful, and just did the preferential activity. Usually, the brand laser engraving has never done preferential activities.
