Hey there. Besides Miku's Headphones, which still exists, the quints' accessories don't hold much significant details/further info to prompt them having their own articles. I do believe that mentioning/slightly describing them in the quints' respective 'Appearance' section is enough.
I made this decision spontaneously though. Maybe you have a reason to keep the articles?
Thank you for the reply! I thought that, being iconic for the Quints, they could be represented separately from the main article. Strolling through forums I saw some posts (very few, it's true!) that treated them individually (butterfly ribbon, matcha teas, starshaped hairpins). But if having those pages creates mess, it doesn't matter!
I had seen them this summer. In one forum it was discussed that Nino and Itsuki used Italian-made fashion (Nino's luggage in seven goodbyes, Itsuki's handbag and glasses-case). Recently I remember something in Reddit (2 requests on where to find Nino's ribbons).
In a German forum it was discussed whether the Itsuki's hairpins would be fashion or not in real life. If you are intetested if I retrieve them I'll send to you!
