Korean lunchboxes

I use to have a large Japanese bento box collection, and I still have some that I use, but I’m curious as to what Koreans carry their lunches in (both modern and hard-core traditional). I’ve seen Maangchi put her lunches in a glass lock & lock container, but is there a Korean “bento” or “lunchbox” that is commonly used? An internet search pulled up only a handful of stainless steel lined children’s lunchboxes highly decorated with Hello Kitty and the like, and the only other results I got were restaurant offerings of Korean lunch specials. Only one picture really intrigued me…it was depicting what it called a traditional Korean lunchbox and was a picture of a small basket-like container that resembled some Japanese boxes but had a more reed-like construction. Anyone familiar enough with Korean history to maybe elaborate on this, or other, boxes?
