Over the past few weeks, many soccer fans have been focused on completing a World Cup-themed sticker album that requires nearly a thousand pieces, which are sold in blind packs of seven.

Interest in the sticker chase in the U.S.

has been picking up over the past decade, and this year is the biggest demand yet.

That's according to soccer journalist Clemente Lisi.

Panini America told NPR that retailers in the U.S.

reported being sold out of sticker packets within a week of the release.
