Floating Balloon Instructions: All balloons cannot float when filled with air; they can only float when filled with hydrogen or helium.Due to hydrogen being explosive and unsafe, we do not recommend its use.Our store's pumps are all air pumps.If you need to float, you can purchase helium elsewhere; our store only sells balloons, not gas
Warm reminder: Balloons and inflatable products have a certain air leakage rate. Wholesale price profit is relatively low. Once sold, there is no after-sales service. Please do not purchase if concerned. Thank you
