Where do I find a glass container?

We suggest reusing a jar you may already have.  We love re-use and upcycling, and encourage you to see if you can find a compatible jar in your pantry or recycling.  For those of you who may not already have a favorite jar, we also offer glass mugs and jars.  You can also buy cases of mason jars at many major retailers.


What type of glass container can I use?

There are so many jars in this world that are compatible with the regular-mouth ring, making reuse a great option with EcoJarz. Here are just a few products that come in containers that might work with your regular mouth EcoJarz:

  • Salsa

  • Peanut butter

  • Applesauce

  • Spaghetti sauce

  • Mayonaise

  • Pickles

What is silicone made of?

Silicone is a flexible rubber-like material made primarily from Silicon (sand/rock) and Oxygen. It has many useful properties and is rapidly becoming commonplace in kitchens all over the world as a high-temperature and inert replacement to plastic. It is a great insulator, does not support bacterial growth, is UV stable, does not off-gas, is non toxic and is highly reusable. You can learn more here:

Are my EcoJarz dishwasher safe?

Yes, both the Stainless and Silicone lids are completely dishwasher safe.  Even in the bottom rack.  

Do you ship internationally?

Yes, we ship worldwide!  However it is more expensive to ship overseas.  While we try to keep our shipping prices as low as possible, please note that the typical price to ship two jars across the ocean is $30 USD.  You will also need to pay the Duties and Taxes on your order, the price of with varies depending on what country you live in. 

Do the color and finish of your products vary?

Yes. All of our products are made to order for EcoJarz, so you might notice slight variations in the product. For example, colors can vary slightly by batch. 

Will the stainless lids rust?

Our Stainless steel will not rust, corrode or discolor under any normal conditions.  However typical jar bands (rings) are often made from a different type of metal and do rust - sometimes quickly.  So if you see rust on your EcoJarz check the band to see if that is where it's coming from.  Rust from the band can be cleaned off the lids by rubbing it with a little bit of baking soda or steel wool.

Our Stainless Steel Jar Bands are made from the same high quality stainless steel that our lids are made from and will not rust, corrode, or discolor under any normal conditions.

How do I clean my EcoJarz products?

For the lids and jars, you can simply scrub them in the sink like any other dish. You can even remove the silicone gasket from the stainless steel lid for deep cleaning.

We now offer a reusable pipe cleaner to make cleaning the straws easier. In addition, you can run this product through the dishwasher, or wash by hand to keep these straws sparkly clean.

Please note that all our products are dishwasher safe.   

Where are your lids made?

Ecojarz is a diverse business!  We have a close relationship with a small Vietnamese company that provides the raw EcoJarz lids to us, and we do all end-processing, finishing and shipping from Upstate NY.  Our products are inspected, processed, assembled and packaged in New York.  Our stainless steel straws are made in Hong Kong.
