This is a great set.  It measure a few thousandths off when I get into anything above a 1/4" just on the small side so I have to shim it into place.  The small guide to the sizes is pretty darn close to right on and is great to use.  The packaging/storage is a plastic case that works great.  I wish there were directions but basically it has shims on one side with the blades and then spacers on the other side with the chippers.  Blades are heavy duty, make a solid cut and a pretty awesome noise on my table saw when it's running
