So good Alexa Chung has given it her handwritten stamp of approval – signed, sealed, delivered. We just know you’re going to fall head over heels for Eyeko's carbon-black liquid eyeliner, complete with WIDELASH lash enhancer. Why? We think Alexa Chung says it best: ‘The nib is the perfect shape and size to give you control. It gives you the precision to draw on the perfect cat eye. It’s pitch black and waterproof so it doesn’t move even on the waterline. I love that it enhances my lashes each time I use it.'
