Domgoge Ocean Number 2 Balloon Tower Set – 40-Inch Foil, Shark & Octopus – Under the Sea Birthday Decor

This ocean-themed number 2 balloon tower set from Domgoge features a 40-inch light blue foil number 2, plus mini foil balloons shaped like a shark, octopus, and bubble fish. Designed for a second birthday party, the kit includes 33 balloons in total, with metallic blues, greens, teal, macaron, and pearl white shades, along with a long balloon, glue sheets, ribbon, and an instruction manual. The combination of aluminum foil and thick latex balloons creates a layered, underwater look that fits an under-the-sea or ocean party theme.

What’s inside the balloon tower kit?

The set contains 1 light blue number 2 foil balloon (40 inches), 3 mini foil balloons (octopus, bubble fish, shark), 12 large latex balloons (12 inches) in metallic blue, metallic green, teal blue, macaron blue, and macaron green, 12 small latex balloons (5 inches) in metallic blue, metallic green, teal blue, and pearl white, 1 white long balloon, 2 glue sheets, 10 meters of ribbon, and a manual. That makes 33 pieces total.

Material and build quality

The foil balloons are made from high-quality aluminum film with a self-sealing valve, so they stay inflated without tying knots. The latex balloons use upgraded, thicker rubber that is non-toxic, odorless, and reusable. The manual includes step-by-step instructions to assemble the tower, and the glue sheets help secure the arrangement on walls or other surfaces.

How do I assemble the ocean number 2 balloon tower?

The included manual shows how to stack the number 2 foil balloon with the supporting latex balloons and the mini foil shapes. The long balloon can be used as a base or connector. You can also use the glue sheets to attach the balloons to a wall or fill them with helium (except the 5-inch balloons, which are too light to float) to create a floating display. The ribbon is enough to tie a cluster or hang the foil balloon.

Versatility for other events

Because each foil number balloon is independent, you can combine sets to make numbers like 18, 81, or 21 by purchasing multiple kits (numbers 1–9 are available separately). This balloon set works for baby showers, weddings, Valentine's Day, anniversaries, New Year's, carnivals, festivals, or photography props. The ocean theme also suits a gender-neutral party.

Care and safety tips

Due to the thermal expansion of foil balloons, do not fill them more than 90% with air or helium. Cold temperatures may cause the foil balloon to shrink; simply re-inflate it if needed. Keep balloons away from sharp objects, high heat, and direct sunlight to avoid popping. The latex balloons may have slight color variation from screen displays. Choking hazard warning: balloons are not for children under 8 years old; supervise use.

Frequently asked questions

Can I use helium with all balloons?

The 5-inch latex balloons are not suitable for helium because they are too light. The foil number 2 can be filled with helium to float. For the larger latex balloons, helium works well.

Is the set reusable?

The foil balloons can be deflated and reused if carefully handled. The latex balloons may be reused if not overinflated or damaged. Self-sealing valves make deflation and reinflation easy.

How do I attach the mini foil balloons?

The mini foil balloons (octopus, bubble fish, shark) have self-sealing valves. You can tie them with ribbon or use the included glue to stick them onto the number 2 or around the base.

What if the foil balloon shrinks in cold weather?

Foil balloons expand and contract with temperature. In cold conditions, the balloon may appear deflated. Bring it to a warmer room, and it will expand again. You can also add a little more air.
