What do they mean by "create 5 free projects"? Will they laser-cut it for you and send it to you by mail?
We don't laser cut anything for you. You can download your project as an SVG file (or DXF, etc) which you can then send to a laser cutter hooked up to your computer.
The product is designed for people who have access to a laser cutter, e.g. at home or at a makerspace.
