Our Princess Mini Crowns are 3 1/2" tall once assembled, attach with velcro to create an opening 3"-3¼" diameter, and have an elastic band to secure as well. These bits of bling come flat and are the perfect child-size party favors and decorations for a princess-theme birthday party. Our gold & silver plastic Princess Mini Crowns are sold in a pack of 12 assorted crowns. Please order in increments of 1 pack.
