As a hesitant buyer I was delighted to discover these foam balls for my Arts and Crafts projects. They are perfect to make ornaments, wreaths, and decorations.The pack includes different sizes and they take paint and glue wonderfully. As a result of my tests, I determined that they hold up well and retain the shape even when manipulated. The only con is that they can leave a few crumbles, but it's not a dealbreaker. Overall, I highly recommend this pack of foam balls..See full review
