发明名称 Dual action tongue scraper
摘要 A dual action tongue scraper provides either a hard scrape or a soft scrape of the tongue, as desired. A hard scraping surface and a soft scraping surface are formed along at least one of the edges of a strip of flexible material. A user bends the strip of flexible material such that generally only one of the hard scraping surface and the soft scraping surface contacts the user's tongue at a given time during scraping.
