These boxes contain eMate Replacement Pens. The box is labeled “24 low-cost replacement pens for the Apple eMate 300 mobile computer.” One of the boxes I have is factory-shrink-wrapped and the other is an open partial box.
The eMate 300, a member of the Newton family, shipped with a stylus of the same design as these replacement pens. Comparing the pen that shipped with the eMate 300 and these replacement pens, the two appear identical.
