Kent & West - PEVA Shower Curtain Liner - USA Made, PVC Free, Clear, Durable 9 Gauge, Bottom Magnets (72" x 72") USA MADE - Our liner is manufactured domestically under high quality standards. This is true for both the material and the assembly. As a company, we prefer manufacturing in the USA when possible. PVC FREE - PVC, or polyvinyl chloride, is the material most commonly used for shower curtain liners. However, PVC releases toxic chlorine-based chemicals which are linked to serious health problems. PEVA is an alternative material which lacks chlorine and is safer for you and your family. DURABLE (9 Gauge) - This shower liner is tough and durable. PEVA is known for being a strong material and our design allows the liner to withstand frequent usage without ripping. It also has metal grommets for added strength. MILDEW RESISTANT - The smooth surface on both sides helps prevent mildew and bacteria from building up. This feature allows the shower liner to stay clean and look new for a long time. BOTTOM MAGNETS - There are three bottom magnets designed to secure your shower liner to your bathtub. Please note that not all bathtubs are made from metal.
