The Top Star ball became a popular design, it was similar to the balls of the time — however, on this ball there were elegantly alternating long and short panels; two short panels in the midst of two long panels and the inflation valve was in the centre of one short panel. The ball brought technological developments as well — the leather balls were treated with a waterproofing wax, making the balls more water resistant. The 1958 World Cup balls were yellow, light brown or white. In matches when it was rainy or wet, the white ones were used.
