IMPORTANT NOTE:  As you can see, this set as packaged is unnecessarily long. This may cause the shipping amount you're quoted to be unreasonably high. If so, please contact me to remove the external plastic packaging, close the blue storage box and adjusting the calculated dimensions for this listing so it will ship at a much smaller size and more economical price!
