Okay, so this Rimmel Wonder'swipe Liner & Shadow in Ballin' 003 is honestly pretty cool. It's like getting two products in one – starts off as this super pigmented metallic liner, then you can totally transform it into a sparkly shadow if you want. The formula just glides on without being all patchy or weird, and you can switch between looks super easily. They've got 16 different shades to choose from, everything from rich metallics to fun bright colors, and it actually stays put for like 10 hours. No joke, your makeup will still look good at the end of the day.This thing really captures that whole London vibe – a little edgy, a little experimental, you know? It comes with 1.7ml of product in this really nice compact design that's perfect for throwing in your bag when you're heading out. You can go with a sharp liner look or blend it out for that shimmery shadow effect – it's totally up to you and what you're feeling that day. If you're someone who likes having options and keeping things interesting with your makeup, you're gonna love this. How to use it: Just swipe it on your lid like you would any liquid liner. Want that sparkly shadow look instead? Just blend it out with a brush or your finger while it's still wet – that's literally it.
