Mine is actually not pink on the inside, but it’s 1” thick. I won it in a raffle from a local salon when I was in high school. I’ve had this straightener for about 5 years now and it still works almost as well as the day I took it out of the box! Sometimes the cord has to be in a particular spot, but not typically. This straightener is excellent since I get a sleek look without frizziness or flyaways. I also frequently use it to curl my hair. All in all, this is a solid product that has lasted me several years and survived several moves. It will serve you well.
