36" Window Box Coco Moss Liner Only

This coco moss liner is 8" deep with built in moisture retention film at lower part of this form. Our coco moss liners are deeper than the steel frame (window boxes, hanging baskets and other planters using this form of inserts) to make sure the top of the liner will not slip under the top ring (rail) of the planter and spill soil and water but keep all inside.
