If you like fancy desserts, this battery-powered decorating pen will be your best friend. It makes it so easy to lavishly decorate, fill, and even write on cakes, cupcakes, cookies, muffins and more. Not only is it easy to do the decorating, this well-thought-out tool is easy, quick, and mess-free to fill and use. It comes with three frosting cartirdges that can be quickly popped in and out to change colors; you can even mix colors right in the cartridges. You get six tips, including a filler tip, ranging from leaf and ribbon to round and basketweave. The pen works equally well with homemade or store-bought frosting. To use, simply fill one of the cartridges with frosting and pop it in the pen, and fit a frosting tip. Then just push the trigger to start decorating; the tiny electric motor maintains a even flow of frosting and stops when you release the trigger. Fun!
