I bought this product 4 years ago forgot about it and used it today. I mixed three colours to get my dark red chocolate coloured leather couch that was just ripped and scratched from pets. I was embarrassed but this product revitalized my couch to like brand new. After sitting for four years only one colour was dry and I just mixed it with a little water over and over and I can’t believe it! Excellent stuff. Finally something decent sold through amazon. This is a family business the card says so good job to the family.
