Levenhuk LabZZ MG3 Magnifier with Compass is a classic model with two lenses and a small compass built into the handle. This is a magnifier for kids, but it is not inferior to adult optical tools. All the elements are made of plastic resistant to accidental damage. It does not have any sharp edges, and is safe for even little kids.
The primary lens is 90mm in diameter and provides 3x magnification. The additional lens is 23mm in diameter and 8x magnification, and is located at the bottom of the handle. The compass is very easy to use, with clear and sharp cardinal points and a dial scale.
