We made a bunch of improvements to the IR Waxer this season. More robust bulbs + filaments. Fine tuned the wavelength for improved wax absorption (nerdy but noticeable). Better heat reflector - sends more heat towards the wax and less towards your hand. Now comes with a sweet travel case.Our patent-pending IR Waxer is a game-changer for at home waxing. It's the tuning tool you never knew you couldn't live without!
