Our buckwheat hulls are an excellent filling because they are a heavy enough and are pliable. No inserted small pockets of beads or sand needed. Even weight along the entire length provides the best seal. Our exclusive winnowing (cleaning) process provides the cleanest hulls possible. Our hull cracking process provides a denser, heavier filling. No loops. Stoppers long enough to properly seal are too long to hang on a door knob. They drag and get caught in the door.
