Sold per slab. Our slabs average 28 pounds. Our beeswax comes directly from the beekeeper. It is then separated and graded according to color. We only use a natural filtration process to clean the beeswax. Our yellow beeswax consists of the dark grades of crude beeswax which are blended together and filtered to achieve the natural yellow beeswax color. Color may vary from lot to lot. Actual slab weight will be used for billing purposes. There may be an additional balance due for the amount of extra beeswax shipped due to the varying beeswax slab weight.
