    Get these instead of AliExpress versions

    Lots of knock-offs floating around out there. Get the real deal if you want your machine components to end us square. These are an order of magnitude better machined than the no-name brand. It may look the same in the pictures but these are actually what you want.

    Great product, nice flush corners. Makes for a very strong corner. Great for cube builds, and smart mirror frames!

    Worked perfectly. Seem to be at least as square as I can measure. Good appearance.
