DC SkyCaps from Skybox International were released in July 1993. DC SkyCaps are based on the Hawaiian milk cap cover game, commonly known as POGs. The series is comprised of 60 caps that depict super heroes and villains from the DC Comics universe. Each cap measures approximately 1.5 inches in diameter.

Packs originally retailed for $1.49. Boxes contain 36 packs. Each pack contains six SkyCaps and one instruction card. Foil-stamped logo odds are approximately 1:6 packs. "DC SkyCap Slammer" odds are approximately 1:36 packs, or about one per box.

Superman appears on #01, and Clark Kent on #02. Both images are from the 1991 Superman Style Guide by José Luis García-López. According to García-López, "Joe Orlando, in charge of licensing at that time, asked me to imitate Jon Bogdanove's style."

SkyBox began marketing DC SkyCaps with a promotional sheet for the "Reign of the Supermen!" story arc. Sealed packs of 50 punch-out sheets were distributed to comic book and card dealers. Early variations of the promo sheet includes die-cut tabs on each disk, similar to milk cap thumb tabs.

The promo was packaged with the June 1993 issue of Tuff Stuff magazine and two-pack bundles of DC Cosmic Teams Trading Cards. The sheet is included with the Limited Collector's Set of The Adventures of Superman #500 (June 1993).

Promo packs for other SkyCaps were distributed at the 14th National Sports Collectors Convention in July 1993. SkyBox printed caps for Batman: Knightfall, Batman Forever, Jurassic Park, Last Action Hero, Malibu Comics, NFL, The Simpsons, and characters created by Jim Lee.

Approximately ten billion POGs and collectible milk caps were sold worldwide from 1994–1998.
