My boarding school in Jamaica did not provide bog-roll ... it was part of your tuck-box kit each term. Referred to as "toosh-pops', it was either "Sandrex" or "Softrex", and it was always a joy to see a Prefect rushing around trying to beg a sheet or three from the junior boys after his supply had expired. *
