Single bag of pine shavings good for 1 Quilt Box. The Pine Shavings in the quilt box will absorb any moisture from the hive in the wintertime so that your bees will not get moisture on the cluster and freeze. Periodically change out the pine shavings when they are wet and put new in so that the quilt boxes do their job and keep your bees alive. We use these on our hives and they work great.
