01 Aluminum foil balloon features:

1) Balloon made of metal film;

2) Rich colors, numerous patterns, with a variety of shapes;

3) With advanced technology, it can be automatically sealed after inflation to avoid air leakage;

In winter, the aluminum thin ball shrinks properly and is not full, and the aluminum thin ball is full when it returns to the normal temperature
