Onyx Containers was conceived after new parents became aware of health compromises everyone deals with when we cook, store, and eat our food. We all know plastic and food is an unhealthy combination. Glass is a good alternative but they have plastic lids and are breakable. Onyx Containers believe that everyone should be able to buy safe and environmentally responsible products without breaking the bank. Their products are of the highest quality, manufactured in responsible conditions and are fairly priced.
If you like our stainless steel mug for your hot bevvies, this is perfect to sip your cold drinks out of.
Its got a 9oz capacity, is made of 18/8 stainless steel, and has a special rolled lip. No sharp edges and its small diameter also make it perfect for little hands and a great transition drinking cup when your small person is growing out of his or her sippy cup and you are not ready to introduce glass just yet.
It's also great for the bathroom too.
