The Foil Balloon School Blackboard is the perfect decoration article for the enrollment party of your child. The best part is that the balloon can be labeled! With a size of 60 x 60cm this is definitely a highlight. The balloon also has an integrated automatic closing valve, eliminating the need for a knot. Just inflate and ready.
The foil balloon can be filled with helium or air . With a helium filling the duration of flight is 5-7 days, with a filling of air the balloon lasts several weeks.
