This two-tier clamp-on desk shelf gives you so much extra room for office supplies, games, or little décor pieces. Just tighten the clamps in your desired location and you'll have storage right where you need it. It’s fully adjustable, too, so you can stack it above or below your desk. Not to mention, it can hold up to 30 pounds without wobbling. Bonus: the raised edges keep everything from sliding off, so your pens, notebooks, or collectibles stay exactly where they should.
