PATIKIL Foam Lid Liners, 500 Pack

These pressure-sensitive foam lid liners are designed to create a secure seal for glass, plastic, and metal jars or containers. Made from polystyrene foam, they offer excellent leak-proof properties, preventing dust, moisture, and dirt from contaminating your products and maintaining freshness. They are easy to apply and peel, requiring no special equipment. Simply clean the bottle top, place the liner with the lettering side up inside the cap, screw the lid tightly, and the seal will adhere within 12-24 hours. Suitable for powder or dry products, but not for oil-based applications. Please verify bottle neck or cap inner diameter before purchase.
