This Applicator is part of the Stick and Shine Collection from Penny Black. This applicator helps add foil to all the Stick and Shine products (sold separately). This applicator is made from hard plastic and is extremely easy to use. Simply take the sheet of stick and shine images, cut one image out, place it on your cardstock, and use the applicator to apply even pressure and release the adhesive. Once that is done, add foil over the top of the adhesive and use the applicator to adhere foil without heat or any other tools (sold separately). This is an extremely easy way to foil your projects. This applicator measures 2.4" x 2.6".
