To give shoes a good clean!
I'm also thinking to buy it to clean my other leather goods and my wife's handbags.
I found that Renovateur in France (Country of Origin) sold for about 11-12 Eu. Collonil 1909 Lotion (COO Germany) sold for about 10-11 Eu, much more like the Reno. & other Collonil products (The premium one) priced same as the Saphir too. By this comparison in price, could we assume that quality of shoe care products not absolutely crowned to Saphir alone? There's a lot of good quality care too in other part of the world, not only in France :P
