WAINLUX K6 Laser Engraving Machine I purchased this and used it three times for testing. I couldn't use it well, and it seems I won't be using it in the future, so I'm putting it up for sale. The box is torn, but the machine itself has only been used three times, so it's very clean. The sunglasses have some minor scratches. Please understand these points before purchasing. 3000mW output, compatible with all items from cloth/wood/leather/food It works with smartphones and PCs, and you can easily engrave by simply uploading images to the app. Engraving is possible on any material, including board paper/cloth/wood/leather/felt/plastic. Easy operation, even for beginners! Compact size allows for easy engraving at home or in the office. I got this through crowdfunding. I ended up not using it and it was put away, so I'm selling it.
