It took eight years by a professional tanner with 27 years experience to perfect this Basic Home Tanning Kit for you. It gives you the knowledge and tools to complete a hair-on tanning process for an averaged-size deer hide. The entire process is completed on a board, leaves minimal mess and doesn't require large vats or tubs. All chemicals are nontoxic and biodegradable. The Basic Kit includes an instructional book, one bottle of tanning crystals, one bottle of tanning oil, hide scraper and sandpaper.
