You can inflate it with Helium or with air. They can float in the room, hung from the ceiling or attached to a wall... the effect is total!
These balloons are inflated with a narrow valve and have a self-closing mechanism. For helium inflation, it is important to have a fine valve and in case of inflating with air you must insert a narrow straw and then tie a knot.
Each package includes an uninflated round balloon and string.
