These arrived yesterday in pristine condition every bearing block was separated from each other and the hardware kits were each individually packaged with the bearings in their own plastic tube. So why is this important to me, because I purchased from another on-line supplier and $300 worth of expensive linear bearings were damaged because they were not packaged correctly. These bearings have most of the holes tapped for mounting which did vary from the print. But now I don't have to tap them. From another review about the hardware varying from the photos I did bring this up to support before I purchased them it was explained to me that it makes it much easier to adjust them with a combination wrench then to try to get a allen wrench between the bearing and the guide rail. This makes perfect sense it may not look as nice as the button head cap screws but makes it easier to adjust after assembly. It is also nice that I can tell that these are proudly made with lots of care every edge is deburred and the bodies have a satin finish to them - this may not be important to some but it all starts with the small things. I know I have purchased a awesome product.
