You don't have to be a princess to appreciate the sparkle of a sequined backpack! Magic Sequins have a double shine - run your hand along it and the colors change! Sequins have a different color on each side and are attached at one end so they flip with the stroke of your hand. Make cool stripes; draw a face or even your initials. The color combinations are as fabulous as they sound (mermaid is a shimmery teal/green/blue mix, pink is hot pink, purple is a rich magenta-violet, & turquoise is a rich blue hue. But how is this going to hold up as a backpack? It's actually more durable than you would expect and should last a while. It may even get your child to be more careful about tossing their bag on the floor. Padded shoulder straps, inside laptop sleeve, front zippered pocket, outside measures 12.25" x 5.5" x 16.5".
