★Guaranteed by Spinist★ Limited Time Offer If it breaks within a year: Exchange it for a new, unused one for an additional 2500 yen! This is a genuine product, so you can request repairs or exchanges from the manufacturer. However, if you purchase from a flea market app, you may not be able to receive a warranty, be charged for repairs, or it may take a long time to get the product back. Therefore, when you purchase from me, I will make a note of your Mercari nickname and the date. If confirmed, I will exchange it for a new one for an additional 2500 yen! No individual price reductions. ★Genuine Adrance Product★ To check for power and operation, I have used the cord to charge it once. Therefore, the cord has been used, but the main unit is new and unused. It has not touched hair or scalp, nor has it been wet, so please rest assured. Please refrain from purchasing if you are overly concerned about this. Please note that I do not keep the original receipt. I will exchange it for a new, unused item in case of initial defects. (I have checked for power, so I don't think there will be any initial defects.)
