Paul shared a pack of Lotte Waffle Biscuits. They were thin and crispy -- crunchy, even -- and sweet, with a little vanilla flavor. It's a refreshing option.
In looking for information on this snack, I ran across a charming website called Biscuit Van. It is written (in barely off-kilter English) by a woman in Japan, and I recommend it for your biscuit-related-reading-material needs.
