If there's one product that really shines out of this entire collection, it's the At The Borderline Eyeliner Marker (£19). The tip is short and easy to handle, so it doesn't tug at the skin and destroy the makeup you've spent over an hour doing. The formula is jet-black, glossy but not distracting, and waterproof. It also single-handedly dismisses the fan erasure of the song "Borderline" on Sweetener.
