Hi Joshua, Blemished binoculars will have minor cosmetic damage (e.g. small scratch, or dings in the outer tube) that do not diminish the functionality. These binoculars are typically new out of inspection, or show stock that cannot be put back into new inventory due to cosmetic damage. These binoculars may or may not have all of the accessories or literature.
Stay safe & have a great day!

Hi Joshua and welcome. Most of these blems are tiny imperfections in the outer finish. These could be small spots of discoloration or dullness spots. According to reviews from other vendor websites, some owners are unable to find the blemish. Blemishes are generally pulled from a lot production and may not affect all units within that lot. Cheers, stay safe and enjoy!
