Hero Arts Color Layering Wreath Clear Design Stamps let you layer colors and images to create unique crafts and cards. This set is part of the Color Layering Collection. Look for a guide on the back for how to use these stamps. Clear design stamps peel off their backing and stick to acrylic blocks for easy positioning. Mix and match the designs, then easily store them for another time. Made by Hero Arts in the USA from genuine photopolymer. Unmatched quality means a crisp impression every time.
