These Silicone Pod Lids (2) make a perfect seal with the Haze Square Material Pods. They serve as covers for pods loaded with extracts on the stainless steel concentrate pads, and can also cover pods filled with herb for travel. Haze recommends the silicone pod lids be cleaned with an organic cleaner instead of alcohol. The Haze Square is no longer in production, but we still stock some limited accessories.
