My husband, god knows how, was searching through my bag (and there was a black pen nearby) and somehow, this inflicted a 4cm long black line on the side of my recently new (3 weeks old) - Blue India Twiggy! I was furious to say the least, and so upset (but he just had knee surgery so I wasn't able to vent my frustration too much)... anyway he felt guilty and told me to try out our leather sofa cleaning kit we had purchased a year ago (it was about 100 bucks okay not too overly expensive)... It worked! The cleaner took the mark away, the conditioner then softened and gave it back its natural shine, and the protector was placed on afterwards to prevent any further marks to the spot. This is the first time I have managed to get a pen mark off a bag and am shocked. I also used the conditioner on my Dark Blue/Navy First that had a dry patch, and this restored it completely... So can sleep easy again.... Any others had amazing stories of saving your bag from potential disaster with household items??
