Our balloon kit contains nylon foil. It can be colorful and glossy, enhance the effect of holiday decoration, and improve the overall beauty. Its use method is very simple: 1. Put the balloon flat on the ground, and then unfold it to find the location of the air nozzle. 2. Put the inclined end of the pump up and slowly insert the air nozzle. Take care to insert the pump under the color film. 3. Hold the front end of the pump tightly and inflate evenly. 4. You can tell that inflation is complete by gently pressing the balloon and finding the bounce. 5. Fold and hide the air nozzle with tape to make the balloon stronger and better gas retention. Beautiful design and bright colors, suitable for children's birthday parties to add a happy atmosphere.
