UNDALO KNOWLEDGE

Standing Number Balloons: Structure & Stability

UNDALO standing number balloons have an integrated base and body. Filling through the base allows gas to flow into the entire number.

One integrated structure

The base and body form one connected structure, rather than two separate parts. Inflate through the base; gas then flows into the body.

Stability in normal use

UNDALO reports repeated testing of the integrated structure and good standing stability under normal use without extra ballast. This is a factory statement, not a numerical wind-resistance or load rating.

Outdoor use

For outdoor use in stronger wind, UNDALO recommends adding ballast to secure the display. Ballast supply or inclusion in the pack remains 【待确认】.

Keep product dimensions separate

The historical 120 cm product designation still needs confirmation of its measurement basis and current finished dimensions. Conventional number-balloon dimensions, film options and floating durations are not automatically standing-number specifications.

Frequently asked questions

Are the base and body separate parts?

No. They are integrated and connected; filling through the base inflates the body.

Does it need extra ballast?

Under normal use, UNDALO states that extra ballast is not needed. Add ballast in stronger outdoor wind.

Does the conventional number size table apply here?

No. Confirm standing-number dimensions separately.
