Crocs Two Strap Slide On Sandals - Size 9

Crocs Two Strap Slide On Sandals - Size 9. Green and Blue. Worn once and in excellent condition. There is a piece of plastic on the strap where "Crocs" button is (see photo). Not sure if it came from a tag that was once on it. I didn't want to pull it off because I wasn't sure if it would break something else. Nothing is wrong with the sandals, just wanted to point that out.
