So called Display calibrator or monitor calibrator. The packaging with mine business card so show the size of the packaging.
It comes with a calibrator stick with USB connector at the end of it. One extension cable and a stand to hold the calibrator all the time.
The length of the calibrator.
In calibration mode.
After calibration based on my office environment daylight. My monitor now is slightly pinkish color as you can see. hehe
