Hello, you can inflate your products by blowing with any straw or with a balloon pump. If you are going to inflate a foil balloon for the first time, we would like to say that it would be beneficial to watch a foil balloon inflation video online first to avoid damaging the lock part of the balloon. � � We recommend that you gradually inflate your balloons, if you fill them with air in an uncontrolled and fast way, it may cause the product to explode. If you are going to fill your products with helium gas, please inflate your balloons 1-2 hours before the day of your celebration, because helium gas does not show its effect for a very long time and when it starts to lose its effect, you may think that the balloon is deflating. If you experience this situation, you can open the lock part of the balloon and re-inflate it, but the balloon will not fly.
