WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
A "One gizmo does all" marvel. It really works as a binocular, magnifier/linen tester, and has a signaling mirror, and compass all in a roughly 1-1/2" sq x 3-3/4" long package. The bino eyepieces and objectives fold against the body with the objectives doubling as magnifiers when used alone. The signaling mirror makes a good examining table for bugs and seeds etc and is conveniently located under one of the lenses. It should make a good "going off to camp" gift!
