Propolinse is a Japanese mouth wash brand. When you rinse with it, what it does is removing the lingering proteins left in your mouth after eating or drinking, then it comes out as strands of protein complexes.
Since it is the Japanese Brand, I put Japanese and English for its product's name. It is better to read the name when the English one is on the right side. In order to read the product's name easily, I use two different colors to cut them in 2 words like "Propo" and "linse".
Black color: for a smoker (whiten & oral hygiene)
Orange color: Regular (halitosis prevention)
