Large Barrel Revlon Curling iron with heat protecting silicon cover

I'm selling all my curling irons snd products because ove come to terms with the fact it will never curl unless its done the sleep overnight way. Unfortunately it's because every time I curl my hair with heat no matter the device the curls go limp in minutes. So this should go to a home where it will be used. This one hasn't been used much and it's not dysfunctional at all but it is old so that may be noticed on opening but it's still super hot and works great just my hair doesn't.
