EUC - 1.5” (1 1/2”) single pass curling iron. Love this curling iron for big beachy waves! Easy to use twist handle and 5 manual heat settings. Cord is perfectly straight (no annoying twists/tangles). Listing because I recently cut 8” off my hair and my new style no longer requires straightening. FYI: I also have a 1” and 1.25” single pass curling iron in my closet - bundle for a whole set!
