Why we love it: T3's famous SinglePass curling iron also comes in interchangeable barrels, using the same ionic technology to seal the cuticle for high-shine curls. It includes a 1" straight
barrel (for defined uniform curls), a 1.25-1.75" tapered barrel (for textured, beach waves), and a 1.5" straight barrel for high-glam, voluminous waves. It's literally three wands for the price of one, and definitely worth the splurge.
