We are the first and only company in the world that has introduced the guarantee seal on the standard 60ml bottles. This element prevents unwanted opening of the tubes, guaranteeing the consumer has an intact and safe product. Our bubbles promise to entertain and delight children for every occasion. Dulcop bubbles are safe, high quality, and easy-to-use with a built-in wand. Great for everyday play, at a party, or afterwards as party favours. For added fun, there is a maze game on every cap! The Hypoallergenic liquid, Kathon and gluten-free is made of purified microfiltered water and biodegradable active ingredients.
