I’ve always wanted to know how they manage to get the red stripes on the white paste, and I always wanted to google it. Today I did. I expected something a bit more exciting to tell you the truth.
The tube has more than one compartment in it, one big compartment for the white paste, and another smaller one for the red paste. keeping each color intact and ready, and by squeezing it you’re applying the red on the white and so the paste come out striped.
