This is an excellent quality powder coating; flat black. Thin smooth surface. You look great! They are cut to just the right length (400mm in my case) and perfectly straight.

If you are building a new machine (CNC or printer), make sure you measure the size you need before ordering. I find it easiest to use them at the advertised length (or…

As a rule, it is not clear from the description what exactly they consist of and whether there are any differences. For the most part, they all appear to be the same aluminum…
