This listing is for one thick sprinkle bangle with rainbow sprinkles. Super light weight and colorful! This inner diameter is 6.3 inches or 63mm. Closer to a standard size bangle. It stands about 20mm or 2 inches thick. This item is 100% handmade by me and slight imperfections may occur. I hand sand and polish each piece and it wont be 100% smooth on the open edge, but I do my best with every piece to make it as smooth and comfortable to wear as possible.
