You're stamping projects will certainly be out of this world when you use the Galaxy Peek-A-Boo Parts Clear Photopolymer Stamp Set by Hero Arts! Included in the set are images of astronauts, planets, shooting stars, and phrases like "To the moon & back," "Sending light years of joy," "Shoot for the stars," and many more. This collection includes a background and “behind-the-window” pieces all in one 6×8 clear set. The set coordinates with the Peek-A-Boo Doors Fancy Die or the Circular Peek-A-Boo Doors Fancy Die to create little windows for messages or the included icon images (each sold separately). The stamps can be used with an acrylic block of your choice and your favorite inks (also sold separately). Made in the USA.
