Glass mason jars in 250mL, 500mL, or 1L sizes with traditional sealer twist caps. All of the mason jars we sell are regular mouth sized openings.

These jars come with a waterproof Harlowe Green sticker for use in our mason jar deposit program. You can choose to buy all of our refillery products in mason jars in each of the product listings; this is an empty jar. To learn more about our program, read about it here.
