Our filters are made from abaca pulp, cellulose and sealing fibers, guaranteeing true-flavor filtering. They are chlorine-free bleached and biodegradable. Without glue or any other type of binding agent. The expanding base of the filter provides the tea leaves enough room for their flavor to fully unfold. Brand new: The box has a large opening for taking out the filters. Reclosable and FSC®-certified. The appealing display is perfect for retail stores by offering more flexibility in product presentation.
