Prevents dust, light, noise, insects, rain, snow and wind from entering through gaps, improving comfort and privacy.

Simple, damage installation and removal—no tools required. Materials & construction Outer fabric: durable polyester. Inner fill: quality PP cotton plus glass beads for added weight and a snug seal.
