MINI CORDLESS DESIGN, GRAB AND GO: Weighing only 234g, this straightening brush is designed for ease of use and portability. The cordless feature means you can use it anywhere without worrying about finding an outlet or dealing with a tangled cord. Its compact and lightweight design makes it easy to bring on the go, so you can always look your best. ONE CHARGE FOR 2-3 USES: This straightening brush features a 3200mAh large-capacity, rechargeable battery that can be conveniently charged using the included USB Type-C cable. With just one charge, you can use it for up to 30 minutes, enough time to straighten your entire head of hair 2-3 times. LESS FRICTION, LESS DAMAGE: The brush's teeth are coated with our exclusive T-GLOSS ceramic material, which is twice as smooth as ordinary materials and reduces friction by 50%. This means that the comb glides effortlessly through your hair without pulling or snagging, resulting in less damage to your hair and a smoother, more polished look. IONIC FOR FRIZZ-FREE RESULTS: This straightener brush releases 50 million negative ions during the straightening process, reducing static and frizz in your hair. The negative ions work by neutralizing positive ions, which are responsible for causing static and frizz, for achieving a smooth, shiny, and frizz-free look without the need for harsh chemicals or excessive heat.
