Perversion Waterproof Fine-Point Eye Pen

I've used this pen for years and they must have changed how its made, because it went from being a 5-star must have item to being a 1-star "what on earth" waste of money. Something is wrong with the capillary action in the pen, so its not that it dries out immediately, but the liquid stops reaching the brush after about 2 weeks. What's frustrating is you can hear the liquid in the pen, you can see the liquid bubble out the side of the pen, but the brush tip remains completely dry. I store the pen upside down and treat it like a precious baby, but still the last 3 I bought were complete trash. Real bummer because this used to be a great product and I do love the brush tip, but its expensively pointless when the eyeliner just leaks out the sides.
