The balloons come Flat (un-inflated). It is best to use a Mylar tap when filling the balloon, but it can be done with a latex balloon tap. The helium can be added by a local party shop, balloon shop or most flowerists. Perfect for the Mickey or Disney themed party. -- Choking Hazard: Children under 8 years can choke or suffocate on uninflated or broken balloons. Adult supervision required. Keep uninflated balloons from children. Discard broken balloons at once.
