Maybelline Sky Tubes Tubing Mascara. Tubing because when you wash it off, the mascara doesn’t dissolve like watercolours but actually sticks together and slides off your lashes like little bits of nylon, spidery thin pieces that end up in your washcloth or on your cheeks, like ash from a house on fire. It’s my favourite kind of mascara, because it doesn’t budge through a 16 hour day and I’ll look tired, but my mascara is still there.
