Our Amish hand-crafted Polywood Barn Wren House is as cute as a button! They are made of poly lumber to withstand those harsh weather conditions. Poly lumber is made of recycled high-density polyethylene materials. It resists splintering and rotting. No need for chemical weatherproofing treatments. It is also impervious to normal wood destroying pests. Our Polywood Barn Wren House is also made with stainless steel hardware. The bottom easily slides out to clean, no tools necessary. Choose from many colors.
