Mason Jar Bugs is a Hero Arts collection of Clear Design Stamps featuring naturalistic bugs and a jar to collect them in! Mix and match the stamps to make fun, creative cards and crafts. Our Clear Design Stamps peel off their backing and stick to acrylic blocks for easy positioning. Made by Hero Arts in the USA from genuine photopolymer. Unmatched quality means a crisp impression every time. Coordinate with Hero Arts Mason Jar Bugs Frame Cuts.
