A simple explanation.

Blind Boxes draws its inspiration from capsule toys and gashapon.

Replace the toys with NFTs

Think: PopMart for NFTs

PopMart is a highly popular platform for collectible figurines, employing a gamified sales approach. On PopMart, artist-designed figurines are sold in mystery boxes, so buyers don't know exactly which item they're getting. Collectors have the opportunity to obtain a variety of collectibles, each with different levels of rarity and worth. The presence of highly valuable items in the mix encourages collectors to keep buying boxes in hopes of securing their desired piece.
