This is NOT a sewing machine manual, it is a printed and bound digital PRINT of a manual. 
This manual is for the XL-5130/5232/5340 series and lists the use and care of the machine.
It includes a section on how to use the accessories. 
Total 69 pages 
The manual has been enlarged to letter size (8 1/2 inches by 11 inches) making it easier to read.
It's printed in color, if the digital copy is in color, on plain white paper.
It is then bound with a clear front and back cover and a comb binding, for ease of reading. It will open flat and can be folded back to the relevant page.
In essence you are paying for the printing, paper, binding, and postage. 
The manual in the photo is representative. Each manual is printed and bound to order.
