卵の殻ステッカー

I doodled little faces on all ten stickers and stuck them on my food containers to see if anyone would try sneaking a bite—the destructible material made it super obvious when one was peeled off.

The marker in the set is a nice touch—I doodled little flowers on mine before sticking one over a jar lid to see if it was opened. Once it’s on, there’s no peeling it off cleanly, which is exactly what you want for keeping things sealed.

Used one to seal a shipping envelope, and peeling it off afterward left a mess of tiny white fragments — which is exactly what a security sticker should do. The set gives you ten chances to get creative, and the included marker holds up better than most cheap pens.
