The Symple Stuff Berumen 10 Gauge Super Heavyweight Vinyl Shower Curtain Liner is crafted of premium heavyweight vinyl. This product is treated with an agent to resist mildew. The rustproof metal grommets and reinforced mesh header protect the liner from tearing around the rings. The bottom of the liner is draft-resistant, keeping it close to the tub walls. Wipe the vinyl shower liner with a damp cloth for an easy clean. We recommend fully opening your liner to dry after each use. Rings not included.
