10mm sanding block

Chis binocular helmet combines comfort, lightness, efficiency and quality. Its 4 high-transparency acrylic lenses (supplied in a protective box) with magnifications of 1.2 - 1.8 - 2.5 and 3.5 clip easily onto a pivoting mounting system, allowing you to keep the helmet on your head even when you're not using the lenses.

4 lens sizes supplied: 1.2 / 1.8 / 2.5 / 3.5

Equipped with two lens attachments, this binocular allows you to combine lenses to provide even greater magnifications (e.g. 1 lens 1.8 and a lens 2.5 = magnification of 4.5).

The light on the top swivels to the right or left and is powered by two AAA batteries (included). Adjustable headband with clip, adjustment of play by two nut/screw systems on the sides (prevents the helmet from tilting on the nose).
