Check out Gamma+ UNO Single Foil Shaver, featuring a gold titanium foil to prevent razor burn, ingrown hairs, and skin irritation when shaving. The close cutting ability is strengthened with forged cutters that remain sharper and can ge through the coarsest hair with ease. Powered by a lithium-ion battery, the UNO Single Foil Shaver can run for 2 hours before a 30 minute charge is needed.
