(Case 00351673)
Hello Robert,
Our ActivPen 50 Pens only come in the dark grey Teacher model and the light grey Student model at present. We will, however forward this as a request for enhancement to the ActivPen devices, to be implemented at a later time.
In the meantime, we would advise the application of an adhesive label to the pen or make other markings on that pen to differentiate pens you purchase from others.
