Take care not to damage the valve when inflating
Keep inflating to iron out all of the seams, the aim is to have completely flat seams and only then will your balloon be round. (Please be assured that with the right amount of helium/air, the seams will completely disappear, just ensure you continue filling the balloon).
Over Filling of Helium / air will burst the balloon.
Self sealing and reusable.
Perfect for all occasions!
