Design is in the details

Why Silicone?
Simply put, Silicone is the only premium material for an eco-conscious koozie. No animal hides or petroleum products here. Just plentiful and easily sourced elements. Silicone can withstand temperatures from below-zero to over 400ºF, is non-toxic and contains no BPA. It can be microwaved. It can be dishwashed. It can be dropped. It can be baked in the oven. It can be thrown off a tall building or from a moving car (although you may have to replace the mason jar inside).

About Us

Our PhilosophySustainability means using less

At Mason-re, we believe that true sustainability comes from using less items for more things. Regardless of how much recycled or post-consumer content a product has, it still takes ENERGY and resources to create it.

This is why we focus on the mason jar - one of the most versatile and reusable products out there. From canning, dry food storage, home decor, and drinkware, the mason jar has hundreds of uses.
