It seems slightly cheeky to talk about a brand that isn't readily available in the UK, but I have found it on eBay, so you could always try it that way!
Even though it is a cult Japanese product, I got mine back in April when I was in Hong Kong. I'd heard about it on youtube I think, and I was certainly intrigued by the unusual wand shape!
I got the Long and Curl version and the combination of the 'bubbled' wand and the curved shape make it hold a curl really well (great for me because I have a weird fear of eyelash curlers). I would however, consider it to be more of a volumising mascara than a lengthening one. There's something about the thick formula that really sticks to the lashes - this stuff doesn't budge (until you want to remove it obviously). I do find that if you try and layer this up, there is a tendency to end up with clumpy lashes, but this mascara does the job in one go anyway so there's no need for lots of layers.
One other thing that definitely needs mentioning, is the packaging! Is it possible to be in love with a mascara packaging? Because I think this is so pretty, and all the variations of Fairydrops mascara are different colours.
Overall, I really like it. It has all the qualities I look for in a mascara, and does an excellent job.
