Styling irons & serum

Hair serum for before use of heat products. Never used. Both the straightener (that can easily be used as a curler) & styling comb (that straightens your hair in less than 10 minutes!) have both never been used either. I just don’t use heat on my hair & have no use for them Each retails for over $300 If interested in just one, some, or all I am open to negotiation!
