Now Tween girls can create works of art that once dry become décor, jewelry or dolls with the new line of String World™ sets! Each themed set includes a pen that comes with over 20 feet of colored string pre-spooled at the top of the pen. As the string is pulled through the pen, it gets coated with adhesive that allows the user to create unique designs that can be worn or played with. Each set has unique string colors and extra elements, such as charms, stickers, and accessories to customize your string creation.
