This is not a toy! This is a research grade microscope. It comes with everything described above and approximately 100 glass slides and glass cover slips, eyedroppers, test tubes, AC power supply, and foam lined accessory box. I do not have original packaging for the microscope but I do guarantee proper packaging for shipment. It is approximately one year old but has been used very little. $500 invested, will take $300 or reasonable offer.
