Hi! I’m the amazing SJ Gang expandable backpack! I like to combine play and comfort to deal with school together with you in a playful way.Have fun making my fantastic plush ears move up and down by pressing the button on the shoulder strap. Have fun discovering them all! It will feel like you have a different backpack every time! I have a large double compartment, which can be easily expanded, thanks to the side zippers for easy storage and organization, even with heavy loads. Thanks to the preformed Ergosystem backrest and the padded shoulder straps in breathable material, I am comfortable to carry on your shoulders, while the integrated bottom ensures that the shape of the backpack remains unchanged and stable, even with a full load.
