While vacationing in the Rocky Mountains and the West Coast earlier this month, I stayed at Quality Inn Metrotown in Vancouver (British Columbia). There, I found my favourite White Swan tissue paper, manufactured by Scott Paper in my home town of Hull (Québec).
I noticed that there are some spots in the paper. Each spot looks like white paint, but I do not know exactly what it is, so I am enclosing a piece of tissue paper for your inspection. The results of your lab analysis would be appreciated.
