True Ceramic Interior Vacuum Insulated Tumbler, 16oz, Original Steel | True Ceramic Lined (Not Coated), Vacuum Insulated, Car Commuter Tumbler for Soda, Coffee & Tea On-The-Go, No Metallic Taste

• True Ceramic – We combine premium ceramic lined with normal stainless steel tumbler (not ceramic inner coating), just a little more weight, no more weird metallic taste. Everything tastes great in ceramic.
• No Peeling – Unlike ceramic-coated mugs, this is real ceramic—not a layer. No chipping and peeling. No scratches from ice cubes. Just long-lasting performance you can trust. Of course it is dishwash safe.
• Keep Temperature – Double-wall vacuum insulated keeps your coffee hot and ice drinks cold. The ceramic lined can not react with carbon dioxide, keeps your carbonated beverage cold and carbonated in a long time.
• On The Go – Slider lid allows you to open with one hand easily. Holds approximately 16 ounces, max to 18oz without the lid. Perfect for your daily drink. And of course this tumbler is BPA-free and Dishwasher-Safe. Please noted that the lid is not 100% leak proof, it may leak if the tumbler is tipped over or if hot liquids cause pressure to build up.
• Standard Sized – This tumbler stands 6.9" tall, has a lip diameter of 3.6" and a bottom diameter of 2.7", It's sized to fit in standard sized cup holders and many kinds of 20oz's accessories.

Real Materials. Real Talk.

Because the interior is made of real ceramic—not a thin coating—it delivers superior taste and cleanliness.

Like all ceramic materials, it’s not as impact-resistant as full metal mugs. So while it’s built for daily use, we recommend handling it with reasonable care.
