Thank you for viewing. This is a set of a dedicated blue touch pen for Challenge Touch, and replacement LR61/AAAA batteries. Selling as a set only. I have already withdrawn from the service, so this is for those who plan to use it! I wasn't very motivated, so I didn't use the touch pen much. Please consider this item as a used product. - Color: Blue - Compatible batteries: LR61, AAAA (1.6V) Thank you for viewing.
