CCTVMTST 2Pcs 8mm x 440mm Linear Motion Shaft Rod Guides Round Bar Case Hardened Chrome Plated

Shipped in wrap, taped together inside a bubble wrap bag. They came out straight without knicks - big improvement over the Anet A8 guide rods which had fouled.

The rails seem like they will work fine and I'm sure I can clean this but these showed up in 2 plastic bags end to end with dirt inside. There is a pine needle or leaf of some sort in here as well. How does this get through any sort of reasonable QC. Would seem to me that these saw the outdoors at some point. I'm hoping its straight and works fine. If I have any further problems with it I'll update the review.

Not like that "8mm" 5/16(7.92) stock that came with my Anet A8 from the factory.Made a world of difference to quality now that the carriage doesn't wobble all over the place.

Arrow straight and very nice surface finish.
