Resizeable/adjustable rings can feel really flimsy but this one doesn't! It's actually a bit hard to size up, though I was being extra careful with it to avoid damaging the color coating. They're also usually very small and I was worried it would end up misshapen but nope! I posted a picture of it next to a size 10.5 spinner ring, it could size up much larger if necessary. I would guess it's probably a size eight without resizing? It was a great way to meet the free shipping minimum and get something out of it I otherwise might not have bought
