Hot tools 1 1/2 inch or 2 inch curling iron

I am not 100% sure if this is 1 1/2 inch or 2 inch curling iron I think it’s 1 1/2 inch Just know when you purchase no guarantee on size Works well It’s been in my bathroom closet for a couple years it is very sticky from hair spray I don’t know how to get that off Oddly I’ve not used it much but it definitely needs a cleaning See photos handle very sticky the gold metal part is hardly used and not sticky like handle
