Balloons are special items and cannot be returned without reason for non-quality problems.

Note: 1. Only helium can fly. Ordinary air cannot fly. 2. At present, there are some smaller sizes (28-inch 30-inch) on the market as 32-inch sales, and their prices may be lower. The impact is that the size after inflation is obviously much smaller, which affects the customer experience, small size helium filling cannot float, pay attention to it
