Enquire at http://www.hairizon.com.sg/Create/index.htm#wivw The WIVV Perm iron is a real stronger curling tong for professionals to create all types of tong curl perm. It is equipped with 3 patent-pending technologies and 9 differentiated functions. Rod size: 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm Black anodised processed barrel. Equipped with ceramic heaters, the WIVV boasts fast heat-up. The anodised plate emits far infrared rays and negative isons, while its elaborate grooves easily comb through hair in winding Extended barrel length: The extended barrel length makes it possible to perform various iron perm techniques Pressure control dial (Patent pending): This helps to regulate the pressure of the clamp in proportion to the extent of the hair damage or sectioned volume, thus working the hairdo in an elaborate way. Turn clockwise to increase pressure, and counter clockwise to reduce pressure. Specially designed clamp for non-slipping of hair (Patent pending): Wave-shaped clamp edge prevents rolled hair from gliding through without using the tail comb for arrangement, in particular, when winding vertically over the barrel. This uniquely shaped tong helps to perform a beautiful wave fast by keeping long hair tightly stick to the barrel Limitless winding clamp (Patent pending): Specially devised heat-reistant pad on the inside of the clamp eases the winding smoothly, being able to repeat it upt to 4 times or more. Sectioned hair keeps tightly stuck to the barrel with even heat distribution all over, thus performing a sophisticated baking Made in Korea
