The unique design and activation make for a completely spill resistant product form start to finish. VOC and REACH compliant. Fits competitors' existing dispensers for easy switchover! Our premium fragrances don't just mask odors, but completely eliminate them with out unique fragrance formulation and technology. Twist fragrances match some of our most popular products such as urinal screens, toilet bowl clips, and hang tags. This keeps a restroom smelling the same, without mixing fragrances.
