I have changed residency programs and I am no longer in the surgical field. I am selling my surgical loupes. They are by "Design for Vision" and comes with the side shield,knit thread, and titanium box. Additionally, I have the lifetime warranty by the company which covers all damages and re-adjustments for the rest of your career. These loupes were only worn once and they are scratch free and in new condition. I am asking for $ 1,100 which is almost half what I paid, but I am desperate to sell because i am no longer in this field. Paypal is the preferred method of payment and I can send all the warranty information to you as well. Thank you
