New data point obtained, gasp!
Looking at photo cards just now, I noticed that Bang Chan is wearing yet another Chrome Hearts cross accessory.
This selfie was taken at the London Hyde Park festival earlier this year.
The bracelet is this one, I think: https://www.therealreal.com/products/jewelry/bracelets/link/chrome-hearts-floral-cross-id-link-bracelet-nc4y3
I don't know if this is the same curb chain bracelet that he's been wearing since 2017, or a different one.
But it does puncture a hole in my theory that he has exactly 7 accessories with this design, one given to him by each #skz member. And it reopens my ridiculous RPF concept where I.N bought the original crossball bracelet for Channie as soon as I.N was considered an adult in Korea.
