LED foil balloons
Foil balloons with built-in LED lights, for eg Valentine's Day and Halloween. The light can be turned on and off, thereby extending the life of the light.
An advantage of foil balloons is that they stay afloat with helium for 1 week or longer :)
Important knowledge: Cold air causes balloons with helium to shrink, but expands nicely again at normal temperature ... Very high heat increases helium emissions!
Note that the prices are without helium, but can of course be picked up inflated with helium from DKK 120, -!
If you want to get them inflated you can simply place an order and write in the Comment that you want to get them inflated and when :)
