5 years+1,000 Orbeez in 3 colors16-page full-color Activity BookletPlay 'n Display Tray The Orbeez Color Pack provides hours of soaking, squishing and showing fun. The color pack contains 1,000 Orbeez in three colors, making 3.5 cups when they are full-grown. Pour the tiny, hard Orbeez into a bowl to soak, and watch them grow over 3 - 4 hours until they are fully grown and uniform in color. The Orbeez can grow to about 100 - 300 times their original volume. They will hold their shape for weeks, as long as you keep in a closed container and away from heat and light. If they do start to lose their shape, just add more water to revitalize them.
