Most appliances have their model number in the 'mold imprint' on the handle. Look for a rectangular imprint in the plastic and find the model number (usually preceded by the word 'Model...'). If the model number cannot be located on the appliance, please call our service center for more information. Call 1-800-326-6247 for a Conair® appliance, 1-800-334-4031 for an Interplak® appliance and 1-800-767-6020 for a Pollenex® product.
