Our brand Bed-bug encasements are tightly sealed with no openings, gaps, or tears and bed bugs cannot escape through. The zipper has very small teeth and are close together to prevent even tiny, immature bugs from weaving in between the zipper teeth and escaping. These encasements come in 4 sizes and in knitted fabric. 

In stock and available for immediate delivery.
