Karaloon - Foil Balloon Number 6 Caterpillar 102 cm - The highlight for the 6th birthday party: Number 6 as a funny snail. 102 cm / 40 inches - Foil balloon made of foil, not metallic - Retail bag with insert. Foil balloon, unfilled, can be filled with helium for an additional charge. Inflated balloons will not be shipped; pickup is only possible in-store. Expert tip: The balloon can also be refilled with a straw by an adult through the valve later with a little air. This saves helium. Warning: Do not inhale or deliberately breathe in helium due to the risk of suffocation. Do not let the balloon fly, as it is conductive and can cause damage to high-voltage lines. Attention! Children under eight years old can suffocate on uninflated or burst balloons. Adult supervision is required. Keep uninflated balloons away from children. Burst balloons should be removed immediately.
