Turns out it's a 1.1 lbs block of wax (17.8 oz). That makes for a great price for the combo pack. I haven't used this block yet, but waxed the kids skis with the all-temp one from the demon multipack and it seemed to work fine. This should be the same stuff, or very similar. The iron works ok, but the temp gauge is hard to get at and it is small. I preferred a friend's Toko that I used last year that was more rectangular with a slight concave edge, which helped flow the melted wax along the middle of the ski. This one instead was the shape of a clothes iron. But at this price, it worked, and it was a great deal.
