Brand and Model: This straight iron is the EH-HS99 model from Panasonic, a trusted brand. It is a high-quality beauty appliance, supported by many users. Nano Care Function: Thanks to Nano Care technology, it is gentle on the hair and achieves a firm, straight hairstyle. It maintains the hair's moisture while providing a smooth finish. High Temperature Setting: The temperature can be set up to 200 degrees, accommodating various hair types. Styling can be done effectively in a short amount of time. The sounds such as "jee-jiji-shuu" from the main unit are the sounds of nanoe being released and are not abnormal. (From the official website) *No box or instruction manual included. Please purchase only if you understand that this is a used item. Operation has been confirmed. There are no disconnections or cord kinks, and the plates are in good condition, so it can still be used. Before listing, I have cleaned off styling product residue and other dirt as much as possible. Also, sometimes there is a crackling sound inside, which is caused by dirt, but I have thoroughly cleaned that as well, so please rest assured. Thank you for viewing.
