End-rounded bristles: For our brush bristles, we have adopted a variety of top-rounding techniques. The protruding bristles on the upper, middle and lower parts of the brush undergo the first rounding process; then the concave part is rounded for the second time to ensure that each bunch of bristles meet the standard. The multi-process is only to better protect your teeth and oral health
Suitable for Home Use: Each brush head has its own color markings, making it easy to distinguish without worrying about confusion
