Rite-Cell foundation is made of durable plastic coated in natural beeswax. Beekeepers love it because it requires no wiring or reinforcement, has sharper cell edges for faster acceptance, and can be used with a grooved top bar or a wedged top bar frame. Because it has a core of plastic, it holds up to extracting and cannot be destroyed by wax moths. Corners can be snapped off along pre-scored edges to create communication holes for your bees. Available in natural or black color, deep or western size. Pack of 10 or single sheet.
