The TP507 Forma Diamond Flat iron is designed with 1.25 inch wide, Diamond-Like Ceramic plates which effortlessly glide through the hair. A temperature control indicator changes color as the heat rises allowing you to easily see the best temperature for your hair type. You can straighten hair quickly with every stroke, locking in moisture and reducing potential heat damage. Hair is left looking smooth, shiny and healthy. It heats up to 450 F in only 20 seconds, has a 9 foot "swivel cord" and a 40 minute, auto shut-off feature for added convenience. The Forma Diamond is also dual voltage (110V / 240V) so can be used for travel. Includes a Turbo Power 1 year warranty.
