Phiten necklace set. The Phiten necklace is approximately 50cm long, the blue rubber necklace is approximately 47cm long, and the black rubber necklace is also approximately 47cm long. Please consider the black & blue rubber necklaces as extras. There is no damage or noticeable scratches or stains, but since they have been used, I will mark them as having some scratches and stains. For those who play sports, those who like exercise, how about a health necklace? Please note that this will be a product-only sale without a box. Please understand that returns and cancellations after purchase are absolutely not accepted unless there is a problem on my end. Thank you for your understanding before purchasing. #Phiten #PhitenNecklace #RubberNecklace #HealthNecklace #Necklace #SiliconeNecklace #Phiten
