Purchased at a pop-up shop in Shinjuku Lumine. One necklace and two rings. These are hypoallergenic accessories. Purchased in June or July of this year, for a total of about 15,000 yen. They are used, but hardly worn. They're cute, but I haven't been able to wear them much, so I'm selling them. I don't know the model numbers, so I apologize for the lack of details. There are engravings on all items except for the double ring. Even the items without engravings are popular items from the brand, so I think it would be best for someone familiar with the brand to purchase them. MELLOW by ayakamori stainless steel accessories, hypoallergenic. This is a complete set.
