I just picked up a vintage Bakelite bangle (I researched the authentic "signs" before purchasing), which I love, but I am a bit hesitant to wear it. I'm nervous about 2 things: damaging it, and the formaldehyde it contains . Anyone wear vintage Bakelite often? What are your experiences with it? I love this one since it has polka dots, and is to me a "find". TIA!
