They need to not overbake them. I ordered 20 packs and each pack is the same. Out of the entire pack there are only 4-7 that aren't rock hard. Just don't bake them as long. I'll not be ordering this brand ever again unless they reduce the bake time. I would always eat these when I lived in Korea and loved them but these are pretty dang hard. I like them moist and chewy. Not really crunchy. :(
