Outdoor Discovery Folding Binoculars are sturdily made of nontoxic, hard plastic material for outdoor exploration with a breakaway neck loop and center focus feature. Easy to hold, these binoculars feature 3X power to bring nature to life in a whole new way and fold up for convenient storage and quick portability. The center focus design makes them usable on close-range objects, is more ergonomic, and allows kids to use both eyes instead of one.
