Chako Lab Insulated Tumbler
570 ml Stainless Steel Tumbler with Detachable Straw
5 Color Options with Gift Box
This 570 ml insulated tumbler is a vacuum-sealed drink container with a 316 stainless steel inner liner and a removable straw. Designed for daily hydration during pregnancy and postpartum, it ships in five pastel colors with optional small cup pouches. The double-wall construction keeps cold drinks cold and the transparent body allows you to see the liquid level.
Why This Tumbler
Transparent Body
The clear outer wall shows the drink level inside. You can monitor remaining volume without removing the lid.
Removable Straw System
The straw detaches for thorough hand washing. No residue hides in fixed straws or valve crevices.
316 Food-Grade Steel
The inner liner is 316 stainless steel, which resists corrosion from acidic beverages better than 304 alloy.
Design Details
The tumbler holds 570 ml (about 19 oz) of liquid. The vacuum-insulated double wall maintains beverage temperature. The screw-on lid includes a flip-top drinking port and a separate straw hole. Both the straw and lid silicone gaskets can be removed for cleaning.
Five pastel colors are available: Sweet Apricot (yellow), Lemon (bright yellow), Baixi (green), Berry (pink), and Jingyue (purple). Each color ships with a thoughtful gift box. Optional variants bundle a small cup pouch in coordinating colors (Little Orange Treasure, Egg Yolk, or Little Lime).

Common Questions
How do I clean the straw and lid?
Remove the straw by pulling it out of the lid hole. Detach the silicone tip and wash all parts with warm soapy water. Use a narrow brush to clean inside the straw tube. Rinse thoroughly and air dry before reassembling.
Can I put hot coffee in this tumbler?
The manufacturer recommends cold or room-temperature beverages only. The transparent outer shell is not rated for prolonged contact with liquids above 176°F (80°C).
Does the vacuum insulation keep drinks cold?
Yes. The double-wall vacuum layer reduces heat transfer. Cold drinks remain chilled for several hours depending on ambient temperature and initial drink temperature.
What is the difference between the gift box and cup pouch variants?
All variants include the tumbler in a gift box. Variants priced higher add a small fabric pouch sized to carry the tumbler. The pouch color coordinates with the tumbler color.
Is the 316 stainless steel liner safe for acidic drinks?
Yes. 316 stainless steel contains molybdenum, which increases resistance to chloride and acidic corrosion compared to 304 alloy. It is safe for citrus juices and other acidic beverages.
How do I know how much liquid is left?
The transparent outer body allows you to see the liquid level through the clear plastic wall without opening the lid.
