It depends on the style you pick. Many character-shaped and Orbz-style balloons are foil/mylar and work with helium for floating displays, or air if you plan to tape, hang, or use sticks. Large standing or base-style number balloons are typically designed for air inflation.

• Check the product description for recommended inflation (helium vs. air) and valve type.
• Use a hand pump or included straw (when provided) for air-fill to avoid overinflation.
• Inflate slowly until firm; stop if seams begin to strain.
• Secure with ribbon or weights as needed and keep away from sharp edges and heat.

Float time can vary based on balloon size, environment, and inflation method. Generally, foil/mylar balloons tend to hold helium longer than latex, but results vary.

• Helium-filled foil balloons often stay buoyant longer than latex under similar conditions.
• Temperature, altitude, and handling can affect performance—avoid extreme heat, cold, and direct sun.
• Using weights helps prevent drifting and tangles that can stress seams.
• For long-lasting decor, consider air-filling and attaching to walls, arches, or stands.
• Always review the item’s details for material and size, which can influence display time.

Bouquet sets on this page often combine a large centerpiece with coordinating balloons, but contents vary by listing.

• Common pieces may include: one large shaped foil balloon plus several round, star, or printed accents.
• Piece counts vary widely (you’ll see sets labeled 5pc, 7pc, 12pc, 15pc, and more).
• Most sets ship uninflated; helium, air pumps, and weights are typically sold separately.
• Some kits may include ribbon; others list balloons only—check the “What’s included” section and photos.
• Review sizing to plan for ceiling height, table centerpieces, or outdoor displays.

Many big number balloons with bases are intended for air inflation and indoor display. Setup is usually straightforward.

• Let the balloon warm to room temperature for easier inflation.
• Use a hand pump to air-fill the base sections first (if included), then the main number.
• Inflate slowly until firm—avoid overfilling to protect seams.
• Secure the base with tape, weights, or a stand, especially near foot traffic.
• Position away from sharp decor and direct sun; adjust ribbon or ties to keep it upright.

Helium services vary by location and aren’t guaranteed for every store or item. It’s a good idea to check your local store’s offerings before your event.

• Many foil/mylar balloons are helium-compatible; confirm on the product page before purchasing.
• If in-store filling isn’t available, portable helium tanks and balloon weights are often sold online and in stores (availability can vary).
• Air-fill designs are a great alternative for arches, walls, and standing displays.
• Review fulfillment options—Pickup, Delivery, or Shipping—on each product page to plan timing.
• Inflate as close to party time as practical for best results.
