The microscope came packed in a polystyrene box with NO instructions on the use and care of the instrument. Also there was NO list of items in the package and some compartments were empty. As a result I am not sure that I have received all parts that you intended me to receive. The outer cardboard box looked as if someone had tore it open and then roughly resealed it with green electrical insulation tape . I can only suspect that customs inspectors may have had to open the package looking for drugs ?
