Reusable water balloons mean no more standing at the sink filling up and tying balloons and no more picking up tiny pieces after the fight is over. These crochet water balloons are made from blanket yarn. This is a thicker, chenille-like absorbent yarn that is 100% polyester. To use these balloons, dunk them in a bucket of water, toss and repeat. If they get dirty, just toss them in the washer and dryer. Not dirty, squeeze out excess water and toss them in the dryer or hang them in the sun to dry. Each balloon measures 4 inches tall and approximately 3 inches wide making them a great size for kids' hands! Each color comes in a pack of 6.
