The secret of this convex-shaped mirror is its ingenious glass: It produces the same refractive index over the entire surface – resulting in a sharply-focused, 10-fold reflection right up to its edges. It’s perfect to deep-cleanse your skin, remove the finest hairs or apply eyeliner. Even in the dark if necessary. 2 x CR2032 button cell batteries (supplied, replacements available separately) provide a minimum of 100 hours of light. Casing made of durable ABS plastic. Measures 12.8 x 9.6 x 1.5cm (5" x 3.7" x 0.6"). Mirror diameter approx. 9cm (3.5"). Weighs approx. 80g (2.8 oz), including batteries. Two suction pads.
