Karaloon - Foil Balloon Number 6 Caterpillar 102 cm - The highlight for the 6th birthday party: Number 6 as a fun snail. 102 cm / 40 inches - Foil balloon made of foil, not metallized - Retail bag with insert. Foil balloon, uninflated, can be filled with helium for an additional charge. Inflated balloons will not be shipped; pickup is only available in-store. Expert tip: The balloon can also be refilled with a little air later using a straw by an adult through the valve. This saves helium. Warning: Never inhale or deliberately inhale 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. Caution! Children under eight years old can suffocate on uninflated or popped balloons. Adult supervision is required. Uninflated balloons should be kept away from children. Popped balloons should be removed immediately.
