so the seed textures really shine through.

Its savory depth makes it versatile.

People slather it on toast, pair it with banana, or sprinkle it over yogurt.

The crunch is the star, just like the name promises.

It feels like a chip but with a milder profile, so it’s great for casual snacking.

At around 13,000 KRW (≈ $9.75 USD), shoppers say there’s plenty to go around

Many admit that once the bag’s open, it’s hard to stop reaching in.

It’s a common pick for kids’ snacks or to keep in the office kitchen.

Priced around 13,000 KRW (≈ $9.75 USD), they keep earning repeat buys

The mushroom aroma won’t be for everyone,

but fans clearly repurchase regularly.
