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. All measurements in the chart are within 0.01mm (which is within the accuracy of my digital caliper; the accuracy is Β±0.02mm). Each of them weighed 166.5g. 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 order them the correct length). Trimming them is easy, but care must be taken to keep them straight and looking very neat. Watch some videos online if you haven't cut this type of splint before. It's a great choice.
