Main Features
Vacuum Insulation
Double-wall vacuum construction maintains beverage temperature. Inner 316 stainless steel liner resists corrosion and does not retain flavors from previous drinks.
Silicone Straw and Handle
Reusable silicone straw prevents spills during transport. Silicone handle provides secure grip when carrying full cup. Straw and handle are removable for cleaning.
770 ml Capacity
Holds 770 ml, approximately 26 oz of liquid. Size accommodates standard drink volumes for commutes, office desks, and daily errands without frequent refills.

4 finishes available to match personal style or workspace aesthetics:
- Lime Sparkling: Mint green matte finish with contrasting straw.
- Peach Oolong: Soft pink matte finish with green accent straw.
- Toffee Latte: Brown matte finish with yellow accent straw.
- Galaxy Soda: Brushed stainless steel finish with pink handle and straw.
All colored finishes feature matte powder coating. Stainless steel finish retains natural metal appearance.
Construction Details
Inner liner is 316 stainless steel, a higher grade than standard 304 steel. This alloy contains additional molybdenum, improving resistance to salt and acidic beverages. Outer shell is 304 stainless steel or powder-coated steel depending on finish. Vacuum layer between inner and outer walls eliminates heat transfer. Silicone components are food-grade, BPA-free material rated for temperatures from -40°F to 446°F (-40°C to 230°C).
Lid design features threaded closure to maintain seal. Straw passes through dedicated opening in lid. All joints and seams are laser-welded to prevent leaks.
Made For
- Daily commuters carrying cold or hot beverages
- Office workers keeping drinks at desks for extended periods
- Users who prefer straw drinking over open rim
- Individuals seeking reusable drinkware to replace disposable cups
Not Suitable For
- Carbonated beverages with high pressure (may force liquid through straw opening)
- Dishwasher cleaning (hand wash recommended to preserve vacuum seal and finish)
- Microwave or freezer use (vacuum insulation not compatible with extreme temperature changes)
- Users requiring measurement markings for precise beverage ratios
Use and Maintenance
Remove lid and fill cup with desired beverage. Do not exceed maximum fill line to allow space for straw insertion. Insert silicone straw through lid opening and secure lid by threading clockwise until tight.
Hand wash all components with warm water and mild detergent after each use. Use bottle brush to clean interior and straw cleaning brush for straw interior. Rinse thoroughly and air dry with lid removed. Do not submerge in dishwasher or use abrasive cleaners on exterior finish.
Vacuum insulation works in both directions: it keeps cold drinks cold and hot drinks hot. For maximum cold retention, pre-chill cup with ice water before filling. For hot beverages, pre-warm cup with hot water before adding final drink.

Common Questions
How long does this cup keep beverages cold or hot?
Vacuum insulation maintains cold beverage temperature for approximately 12-24 hours and hot beverage temperature for 6-12 hours, depending on starting temperature and ambient conditions. Performance decreases if lid is opened frequently.
Is the silicone straw dishwasher safe?
No. Hand washing is recommended for all components including the silicone straw. Use a straw cleaning brush to reach the interior. Dishwasher heat and detergent may degrade vacuum seal over time.
Can I use this cup for carbonated drinks like soda or sparkling water?
Not recommended. Carbonation creates pressure that may force liquid through the straw opening in the lid, causing leaks or spills. Best used for still beverages, coffee, tea, juice, or water.
What is the difference between 316 and 304 stainless steel?
316 stainless steel contains 2-3% molybdenum, which improves corrosion resistance compared to 304 steel. This makes 316 more suitable for acidic beverages like citrus juices or coffee and provides better durability in contact with liquids over time.
Does the cup fit in standard car cup holders?
Cup dimensions depend on handle orientation. Base diameter is approximately 3 inches (7.6 cm). Most car cup holders with 3-3.5 inch diameter openings will accommodate the base, but the silicone handle may require adjustment or removal in tighter holders.
Can I remove the handle if I prefer not to use it?
The handle is attached to the exterior finish and is not designed for removal. If a handle-free design is preferred, consider alternative drinkware without handles.
