These balls come in many colors and interesting shapes. Some like the Crater ball has finger holds while the Bubble ball has bumps. You might also like the Fashion balls with swirling indents that make them easier to grasp. Or look for the ones with alphabet letters, geometric shapes, or numerals molded into their surfaces. They are the size of a softball and make a nice impulse toy that leads to active play.
