Now your room will have a cozy atmosphere - with your self-made string of lights! Here's how it works: Inflate the balloons until they have a diameter of about 7 cm. Then, soak the nylon thread in a mix of glue and water and wrap it around the balloons. After 12 hours of drying time, you can pop the balloons, connect the LED string lights with the balls, and the light magic is ready! A detailed guide will explain each step to you - so nothing can go wrong! Suitable for ages 6 and up. Made in Holland!.
