Many moon foil and latex balloons can be inflated with helium to float or filled with air for longer indoor displays. A few large astronaut or air‑fill balloons are intended for air‑fill (non‑floating) display.
Designs include glowing moons and crescent moons (often used in Halloween displays), bat‑and‑moon graphics, and moon foil pieces included in space‑themed sets.
The matching latex balloons included with several moon foil sets are typically 11 inches.
Most product details list the suggested age as 10 years and up.
The shaped or printed moon balloons in these listings are made from foil; sets commonly include matching latex accent balloons.
Counts vary by listing: many sets include 3, 4, or 6 matching latex balloons (a range of 3–6), while some foil packs are sold as 2‑pack foil without matching latex.
Moon‑themed balloons are commonly used for Halloween parties, haunted houses, and trick‑or‑treat events, as well as kids' birthdays, space‑themed parties, and sci‑fi events.
