Shipping method: Yu-Packet Plus (Yu-Packet Plus dedicated box may be a recycled item) ● Advanced linear sonic vibration with a 20% power increase. The advanced linear motor achieves 31,000 brush strokes per minute of linear sonic vibration. Furthermore, the motor's power is approximately 20% higher than previous products. It removes plaque more efficiently in a shorter time than a manual toothbrush, leaving the tooth surface smooth. ● 1mm reciprocating motion that replicates professional brushing. It is important to move the toothbrush with small reciprocating motions to remove plaque. Prinia Slim has an ideal 1mm amplitude (reciprocating) motion. It can reproduce efficient professional brushing without damaging the gums. ● 3 selectable amplitude modes The brush amplitude is 'Normal (1mm amplitude)' for ideal brushing. In addition, 'Soft (0.7mm amplitude)' and 'Super Soft (0.45mm amplitude)' are also available for comfortable use, even for those who are using a sonic toothbrush for the first time or those with gum inflammation. ● Slim body that is easy for women to hold The body is even slimmer compared to previous products. It is easy to hold even for those with small hands, and can be used comfortably by children, women, and the elderly. In addition, the toothbrush has a compact head, making it easy to move around in the mouth and efficiently brush even the smallest areas. ● Convenient timer function It pauses temporarily approximately every 30 seconds from the start of brushing to indicate the brushing time. ● Excessive pressure prevention mechanism If the brush is pressed too hard, the brush amplitude will automatically decrease. Safety Warning This toothbrush can be used by children. When used by children, it should always be used under adult supervision. Also, if the brush is pressed too hard against the mouth, the brush amplitude will automatically decrease, so do not apply excessive force.
