These would be a great first pair of binoculars for a child. the optics are clear but not as good as my other BAK4 bins (both larger ) Finish is not perfect but good enough and construction appears to be all plastic, though this keeps the weight down. I bought these for a bright 7year old who, as a keen nature observer was be delighted to have them.
