Product Description (Quoted from the website) * Brand: KAI * Features: Waterproof * 【Dedicated Razor for Delicate Zones】 A razor for VIO (bikini area) for complete hair removal. It removes underarm hair to reduce discomfort such as stuffiness. Provides peace of mind for swimwear styles at the gym or beach. * 【Gentle on Sensitive Skin with Sonic Vibration】 The blade moves in a circular motion with sonic vibrations of approximately 100 times per second, reducing resistance to the skin, allowing for a shave with a feeling like a gentle caress. Battery operated (1 AAA alkaline battery). * 【Small Head for Smooth Detailing】 The mini blade with a film guard that is gentle on the skin allows for easy maneuverability and smooth care of the VIO zone. Comes with an aloe smoother for a smooth feel. * 【Allows for Grooming with a Comb】 A wide comb is incorporated at the bottom of the small head blade, allowing the comb to separate long hair and complex hair flows for a clean shave. * 【Water-Resistant for Easy Cleaning】 It can be washed with water, allowing you to keep the product hygienic even after repeated use. Note ⚠️ I have used it a few times. Replacement blades (sold separately) are available for purchase. Thank you for viewing.
