Oh Happy Day by Lia is a Hero Arts collection of Clear Design Stamps featuring a variety of frozen treat images, perfect for creating stylish cards and crafts. Our 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. Designed for Hero Arts by artist Lia Griffith.
