Directions
Sangi's directions for the tube, in three moves.
Put 1 to 1.5 cm of paste on the brush. That is 0.4 to 0.6 inch, less than the length of most brush heads.
Brush teeth and gums gently and with care for about 3 to 5 minutes. Sangi suggests brushing after each meal, 3 times a day.
Spit, then rinse lightly. The directions say a light rinse leaves some of the paste's hydroxyapatite behind in the mouth.

Box seal arrived open
I am concerned tmof this is authentic as the seal came open and dirty (see photo) but the toothpaste is sealed. Also the tube has a made in Japan sticker on the front. I want verification this is correct packaging as i haven't ordered this one before. I use the premio or m plus.
