Platform Crocs size J5

Brand New never worn big kids size 5 platform Crocs black with colorful stars and a colorful strap. I wear a women's size 7 crocs and usually wear a kids 5 in them however these seem to be made on the smaller side so I would go a size up in these. I stupidly ripped the tags off and threw them away assuming they would fit so these are brand new and have never been worn.
