Co-Goods 18x Smartphone Telephoto Lens Monocular Telescope Smartphone Lens I purchased this and tried it once at home, but I changed phone models before I could use it in the field, so I am selling it. You can use it as a monocular even without attaching it to a smartphone. All accessories that are outside the case are unopened. The main body has no noticeable scratches or stains and is in overall good condition. Please check the second photo for compatible models.
