The harm plastic is inflicting on our bodies and our planet is old news. But change is tough. Ditching plastic -- especially the single-use variety -- can be overwhelming. At Mason Jar Merchant, we believe swappin’ plastic for glass is the best way to start your low-waste journey.

Here are a just a few of the reasons we LOVE glass:

  • Earth friendly and sustainable alternative to reusable plastic water bottles
  • Endlessly recyclable and surprisingly durable
  • Beverages taste much better in glass than in plastic or stainless steel
  • No nasty toxins like BPA leaching from plastic into your drinks

Perfect for smoothies, iced coffees or simply as a water bottle with a straw, a glass mason jar is the healthiest choice for your body and the environment.

Great for travel, just throw a flat wide mouth canning lid under the straw lid of your drinking jar and it's instantly sealed and leak-proof.

Once you go glass, you’ll never go back!
