One of my favorite products from MAC is definitely the 3D Silver glitter, obviously, it's on my blog's header (which, btw, I'm planning to change). This is a multi-colored glitter in silver base. It's meant to be used on the body, lips, face (like cheeks) and nails. It's not safe for use on the eyes but I use it sometimes, you need to be very careful when using it on your eyes. To apply it you just have to use a sticky base like a glitter adhesive. I use Mixing Medium Gel by MAC. 3D silver glitter is ideal for party and night out makeup.
I love how it sparkles!
Do you use glitter on your eye makeup?
