These binoculars are 10x more compact. Perfect for live events and bird watching. There are no adjustment buckles on the strap, so please prepare one separately or tie it to the hook. We are sorry, but there are no instructions for this product. ‼️I have only used it a few times, but there is some wear and tear. Please understand that this is a used item, and only purchase if you are okay with that. Thank you for looking. #Binoculars #LiveEvents #CompatibleWithGlasses #BirdWatching #Birdwatching #Outdoor
