This package of three Heart Acrylic Dividers is part of the Memory Dex Collection from Clear Scraps. These shapes include one large heart, one divider with three hearts on top, and one divider with a heart cut out on the top corner. These acrylic pieces have a protective film on both sides that needs to be removed before embellishing. These heart laser-cut shapes fit into the Memory-Dex boxes (sold separately) and glide easily over the rails system. These dividers will work with most Rolodex and other systems (sold separately). These dividers measure 4.0" x 4.0". These dividers are made in the USA.
