Frequently Asked Questions
Is this authentic?
Yes. We only buy from official retailers and directly from the brands here in Japan. Never resellers, never grey market stock.
We are beauty lovers too, so we know the worry, especially with something you are putting on your face. Authenticity is 100% guaranteed by us.
What does the silver-ion (Ag+) treatment do?
It helps limit bacterial growth on the bristles, so the brush stays more hygienic in a humid bathroom between uses. It is a cleanliness feature, not a replacement for rinsing and drying the brush.
Are the bristles soft?
Yes. They are very fine and feather-soft, made to clean gently along the teeth and gumline, which suits people who prefer a soft brush or have sensitive gums.
How should I brush with it?
Angle the bristles at about 45 degrees to the gumline and use small, light strokes of a few millimeters, spending a couple of seconds per tooth. Avoid pressing too hard, which can harm gums.
What is included?
The set includes two toothbrushes in grey plus a case, so you have a spare and a way to carry or store them cleanly.
