Select your preference at checkout. Important — coat with molten wax before use: Plastic foundation requires a thin coating of molten beeswax applied to both sides before placing in the hive. Without it, bees are reluctant to draw comb on the plastic surface. Melt clean beeswax, brush or dip to coat, allow to set, and the frames are ready. This one step makes the difference between frames that are drawn out quickly and frames that sit ignored.
