Our cork stoppers are adorable and make accessing the contents of your jar super easy! Use for anything – food storage, crafts, or home decor. We hear they are even good for cleaning your smooth-top range! 4 cork lids per order. Sets of 4 regular or wide mouth cork lids come in paper (retail ready) boxes. Combo regular and wide mouth cork lids do not at the moment. Combo 4 pack is 2 regular mouth and 2 wide mouth. These cork lids will really make your jars pop! Cork is a natural material so colors vary slightly. The regular mouth corks are 62.5mm at the top and 58mm at the bottom. The wide mouth corks are 76mm at the top and 72mm at the bottom. They are both 28mm thick. Food safe. Made by forming small bits of cork with steam and pressure, the same way that composite wine corks are made.
