Brand new UGG Boots australia size childs 13. !

bought these boots from a friends mother for my neice about 2 month ago . found out that i bought the wrong size. i have no idea about ugg boots except that every girl wants a pair .. this pair has never had a foot in them , there is no tags on the boots except for the ugg australia sbadge on the back of the boot . they are suede outside and fur in the inside . They came in a canvas bag with the UGG australia sign on the bag . If you have any questions please give me a text or call thank you David
