If you do not inflate this year and wish to store away for another year will they self inflate next year or is chemical done within a year?
Don't know. This is the first time I purchased the balloons so I don't know how long the packets inside the balloons will last. However, one of the balloons I received did not inflate; in fact, there must of been a hole in the balloon because the liquid spilled out. This may have been a defective one.
