LOKIPA White Foam Balls,3 Large Styrofoam Polystyrene Spheres Balls for Art Craft Decoration Balls to Household School Projects

My son has to make a solar system for school. Thank god for Amazon prime... these balls were here the next day and ready for painting.We bought the really large one separately as we needed one much bigger, but the rest all came in the pack with lots left over. Although there were more smaller ones and only a few bigger ones. They painted pretty well, some took more coats than others although don't know why as they seemed the same texture. We used Baker Ross acrylic paint as that's what we had in the house, but there may be a better paint for polystyrene... something slightly thicker perhaps.Worked really well so I'm happy with the purchase.
