Diameter Measurments were extremely inconsistant due to a diameter that changes alot along the length of the line, so its hard tio tell if this really is an “ultra-cast”.
The surface of the line is generally quite smooth but it does look like it has some kind of coating, or perhaps it is the “cold-fusion process” that is claimed to be done?
During handling, the line dye came off and made my hands a nice multicolor.
