Thank you for viewing! This is a beauty device! It is not a medical device. It is not a needle; it is made of silicone. It is a micro-needle pen. I purchased it from Beauty Garage in August for 88,000 yen, but it didn't fit my salon's menu, so I am selling it unused, only tested for functionality, at a discounted price. It requires dedicated disposable tips, and I will include 20 dedicated tips. Since 5 tips cost 3,850 yen, that's a 19,250 yen value as a gift. Replacement tips can be purchased from the manufacturer. There are video tutorials available on how to use it, so it seems easy to operate. It seems suitable for introducing Lemon Bottle. For detailed product information, please see Esthe Derma from Beauty Garage. I turned it on to check the functionality, so I appreciate your understanding.
