Dear Sirs, I purchased a mascara recently, shown below, whilst in Switzerland. I bought it on a whim because, if I'm honest, I was attracted by the design of the lid! It's not my usual brand. After a couple of uses I liked it and thought to myself that I would definitely switch to this one. However, I travel a lot. Quite quickly the strangest thing started to happen. First of all I had mascara each time in my makeup bag . The mascara expands exponentially! First few times it settled down and was useable but now it doesn't. It stays like a viscous foam on the brush. Clearly I've used hardly any of this mascara, there's loads left but it's unusable. I'm rather disappointed. It hasn't been subjected to any extremes of temperature, any extremes of treatment at all. It's a well known brand and not inexpensive!
