Thank you for viewing. This is EFFECTOR's booster. I purchased it about 7 years ago for my collection. I used it about 8 times and then stored it at home. The lenses do not have prescription. There are some minor scratches from use, but there is no distortion or looseness in the hinges, and it is in relatively good condition, but please check the images for the condition. As a bonus, I will include a separately purchased hard case, but please note that the case has scratches. When shipping, I will wrap it in bubble wrap and ship it in a cardboard box. This is a used item, so it will be sold as is. Please check the condition in the photos and purchase with your understanding. Please refrain from purchasing if you are sensitive to details. No claims and no returns. MODEL: booster Collaboration with the Japanese rock band, abingdon boys school. Based on the fuzz, the design lowers the temple position while maintaining the volume of the fuzz. SIZE W155mm-47Hmm Lens-W52mm Lens-H38mm Bridge-H21mm Temple150mm
