SKZOO and Sanrio turned a stamp into a mystery pull because apparently stationery needed photocard energy too.

The Stray Kids SKZOO x Sanrio Characters Secret Block Stamp comes in one randomly selected character design from a lineup of 16 possible SKZOO and Sanrio characters. Open the block, reveal your stamp, and immediately decide whether one mystery was enough.

Tiny stamp. Full pull-reaction behavior.

WHAT MAKES THIS SPECIAL

The Stray Kids SKZOO x Sanrio Characters Secret Block Stamp combines three powerful collector concepts: character merchandise, stationery, and the emotional uncertainty of a mystery pull.

There are 16 possible designs featuring individual SKZOO and Sanrio characters. You will not know which one you received until the packaging is opened, giving every box the same suspense as pulling an album inclusion. Except this time, the result can stamp your planner.

Each block has its own character color scheme and hidden stamp design. The compact shape also gives it display value beyond its stationery function. Line a few up on a desk, attach one to a suitable accessory, or keep the unopened box nearby while pretending you are not thinking about the possible pull.

The mystery format makes every character reveal feel like a tiny event. Pull your favorite and celebrate. Pull another character and discover that your collection has apparently chosen a new direction for you.

One stamp is fun. Chasing your bias is where the collector plot begins.
