Ordinary clippers have a limited range of motion and make it impossible to clearly see what you're doing. Wonder Clippers™ have a built-in light, and the head swivels 150º so you can see clearly and cut confidently from any angle. The easy-to-grasp handle gives you increased leverage, and the stainless steel blades are extra sharp so you can cut through the thickest nails with ease. Wonder Clippers make trimming fingernails and toenails precise and easy. Requires 3 button cell batteries (not included). Plastic and stainless steel. 4"L x 1 1/4"W x 1 1/2"H.
