The Jarware Mason Jar 2-in-1 Regular Mouth Drink Lid makes your average canning jar into the best drink cup ever. Simply add your favourite fruit, fresh herbs, or vegetables to the jar, add water, and top with the lid. The water infuses with your added flavours without you having to filter it through your teeth. Made of 18/8 long lasting stainless steel with silicone seals, this drink lid is top-rack dishwasher safe. This Mason jar accessory fits wide mouth jars. We recommend a 16 ounce Ball, Kerr, Kilner or Anchor Hocking jar for the best results.
