Compatible with Full Depth wooden Hoffman grooved frames. Plastic foundation made using an extrusion process is the premium product. Just the right combination of flexibility, strength and rigidity in the thinnest plastic foundation you can buy. Thin foundation means less plastic and more honey.
These sheets are already coated with a thin layer of beeswax. Just pop them into your wooden frames and you are good to go.
