H&M girls bangles (each set comes with 3 gold toned, 2 black, 2 white, 1 glitter and 1 silver toned)
Item #94961 ($3.95 for the set)
I walked over to the girl's accessories department and scoured the entire area and couldn't find another set. I did however find a similar set w/different colors that had the same price tag but they were much too childish. It was confirmed that indeed it was from the girls section. I found an SA and asked for her to help me find a 2nd set of bangles because I knew I wanted 6 gold ones and there are only 3 in each set. She was super sweet and helped me dig and dig until we were both sweating. I figured I will just buy the one set and look for a 2nd set at a different location. As I was standing in line, the same SA came up to me holding a 2nd set. I must have screamed so loud that people thought I was insane. I was so happy. It was a good day!
Diameter is 2 1/8" (even smaller than a size 2 1/4")
If you don't know if these will fit you, as a reference my wrists measures right under 5 1/4" and from knuckle to knuckle is 2 1/4". Use Kelly's oldie but goodie post here to measure what size bangles will work for you.
The only downside to these is obviously the quality. I can see where the ends were soldered together and I'm not sure how long they will last before either they break or the gold/silver tone will wear off. For the price tag of $3.95 and how perfectly they fit- I think I'll chance it! I'm already wearing them : )
