Review (4/5): Hard Case for Iron
This is perfect for my BaBylissPRO Nano Titanium Spring Curling Iron that's 1 and a 1/4 inch. I have an Instyler too, and I plan to buy another one of these.
One thing though, it's not small nor compact. It's perfect for at home, but when I'm flying or traveling this is a bit bulky (despite the name) though that might just be a personal preference. It definitely keeps it safe though and I love the hard case.
