Rugby Attax Worldstars 2015 was a collectible card set published by Topps timed to coincide with the 2015 Rugby World Cup held in England. The World Stars variant was aimed at markets outside England, differing from the domestic Rugby Attax England 2015 release primarily in its limited-edition card selection. The full set comprised 240 cards, with each card featuring a player photograph alongside statistical ratings for passing, tackling, kicking, breaking, speed, and strength. Retail products included starter packs, nine-card packets, and five-packet multipacks with a limited-edition insert. The range was available from 13 August 2015. Topps positioned it as the only officially licensed 2015 England rugby card collection on the market.
