The price is per sheet/stick, you have to select the width and length then it shows the price. The prices look pretty good. The weight describes the density. This is medium to heavy density balsa. (7-12lb)

I have not tried them but I may. Balsawoodinc also has great prices and I have ordered from them and the woog quality was very good. All the sheet stock was uniform in thickness and was nice and straight.
