Gamesense Radar 3mm. I purchased this from Arc and used it for approximately three months before storing the outer box in a dark place. I am selling it to declutter. - Price: I am willing to consider some price reduction as I want to sell it. - Usage Period: Approximately three months. - Condition: As shown in the photos, there are some stains. I haven't found any other noticeable stains, but please understand that this is a subjective assessment. - Notes: Please only purchase if you understand that this is a used item. Also, please understand that I cannot ship on weekends and holidays, and will generally ship on weekdays. Please feel free to ask any questions or discuss price reductions in the comments.
