Remove TOKII brush & holder from package & set it on your counter.
When ready to brush, gently pull TOKII stem forward as indicated by downward arrow & lift it out of the holder.
As in picture, press upper knobs (a) with thumb & index finger.
With the other hand, slowly pull out the TOKII scraper.
Leave scraper aside & start to brush teeth as you normally would.
Now take the scraper & reinsert into the stem only till knob (b). You will hear a click sound indicating that it is locked in place. Invert the brush head outward & the scraper near the mouth.
Extend your tongue out & place the scraper to the end of your tongue near the throat as far as it is comfortable.
Pull the scraper gently & yet firmly from back to front in a long single stroke removing the white coating from the surface. Repeat this downward motion also scraping the sides of the tongue too. Do this at least 7 to 9 times throughout the mouth. You can wash the scraper every time you see a heavy buildup being scraped off your tongue. It may feel weird the first few times if you have never done this before. Soon, you will get used to this & start feeling fresh & healthy as the pink of your tongue starts to show.
Wash scraper thoroughly & rinse it well under running water.
Reinsert scraper all the way into the TOKII brush stem.
Put it back on the TOKII holder.
