Bandori Rings

Hi I hope its not a problem to ask this here, I've used reddit like once in my life so forgive me if I'm asking in the wrong spot haha 😅 I'm looking online for resales of the rings produced around 2020, particularly Aya's and am unable to find any listings... Ive checked ebay, mercari en and jp, jp yahoo , and a couple other sites but I'm not seeing any listings. I tried to search with "バンドリ/ガルパリング" or "丸山彩リング" but to no avail. I'm wondering if anyone has any site recommendations or if perhaps theres a better keyword to search; I don't know much Japanese so unfortunately I'm not sure if theres a better way to phrase this. Again I hope this is an appropriate place to ask and if not just let me know and I'll take it down. Thank you! 🥹
