In addition to all the normal features of Knockaround Premiums, Goal Line Premiums feature grass green fronts, white arms, and amber lenses. Only thirty pairs were produced; each pair comes with a numbered edition card, a hand-folded, copper-tinted paper football, and a ref's whistle (so you can keep your opponent in check). Everything is sealed nicely in a powder blue, mesh jersey pouch. All right, now buttonhook left on three...hut, hut...HIKE!
