Blister Pack
A blister pack is a retail package of one to three booster packs mounted on a hanging card, often including a promo card or coin.
Blister packs are the booster products you see hanging on pegs at supermarkets and big-box stores: one, two, or three booster packs sealed against a cardboard backing, frequently bundled with a coin or an exclusive promo card.
Per pack, blisters usually cost more than a booster box or bundle — you pay for the packaging and the promo. Their real appeal is accessibility and those exclusive promos, some of which are only available in specific blister waves and become collectible on their own. A niche nuance: some collectors seek "heavy" vintage blisters kept sealed, since the backing card protects the packs and proves the product's origin.
