The TP deal is no joke (Put it in the wastecan, not in the toilet). I haven't been to Russia, but lived in South America for 18 years. Their sewer systems (if they actually have one) are often not built to handle the paper, and the paper is more like sand paper. The Sears & Roebuck catalog is softer than a lot of the paper they use. In one city where we lived, after the city sewer project was completed they were so impressed that they erected a huge piece of sewer pipe in a public park as a monument to the sewer.
