Sets are available in black or multicolored options. Some packages specifically list Black, Blue, and Red.
They use chisel tips and are described with a medium point size.
The packaging lists a suggested age of 18 years and up and includes a CPSC choking hazard warning for small parts.
Sets are described as including bonus refills—typically two—often listed as black refills or a mix such as black and blue.
They produce vivid, dense writing with a steady, smooth ink flow that stays uniform from first to last stroke and remains clearly visible from a distance.
The ink erases easily and is formulated to leave little or no ghosting while producing bold, long-lasting lines.
