【Easy Dial Height Adjustment Section】 Height can be adjusted in 0.5mm increments from 0.5mm to 2.5mm without attaching any attachments. (Recommended as a Christmas present for your father) 【Battery Level Indicator】 The charging status is clear at a glance, allowing for better haircuts. 【Waterproof Function】 The clipper body is fully waterproof, but the battery is not. Therefore, it's best to securely close the battery cover before washing with water. 【Cuts in One Go】 The blade tips are made of high-quality stainless steel and ceramic, and the sharpness is excellent. High vibration frequency, outstanding cutting performance, and a beautiful finish. Note: The newly arrived clippers only have a built-in battery, and a spare battery is not included. Please confirm before purchasing. The transport of liquids is prohibited for international shipments, so the clipper oil is not included. It can be purchased separately on Amazon. Clipper body: If you have any problems or questions during use, please feel free to contact us. (The blade part is a bit sharp, so please be careful during use.) Y027
