Thin thin not very good, not good for dinner
Size: 1000 Count
They say online they are dinner napkins, but when they arrive they say Luncheon. These are so thin, not good at all unless you're eating a piece of toast .

Good quality and value!
Size: 12 Packs, Style: Lunch Napkin
Less expensive than the same amount of napkins at our local BJ’s. Bought my first box for my son’s grad party (a few years ago) and I’ve been buying napkins this way ever since.
