Pokémon Blisters

Blisters hold one to three English booster packs and one or more promo cards in clear plastic, so you can see the promo before you buy. They come as checklane blisters, premium checklane blisters and 3-pack blisters, all with packs from recent sets.

Plenty of collectors buy blisters just for the promo. The exact contents of each blister — packs, promos and any coin — are listed on its product page.
