Stainless Steel Insulated Tumbler with Straw
Double-wall vacuum construction holds 20 oz (590 ml)
This stainless steel tumbler uses double-wall vacuum insulation to maintain beverage temperature for extended periods. The 20-ounce capacity fits standard cup holders, and the included reusable straw with silicone tip works with cold drinks. Available in blue, pink, and yellow powder-coated finishes that resist scratches and provide grip.
Core Features
Temperature Retention
Double-wall vacuum insulation keeps cold beverages cold for up to 24 hours and hot drinks hot for up to 12 hours. The airless space between walls prevents thermal transfer.
Durable Construction
18/8 food-grade stainless steel body resists rust and maintains taste integrity. Powder-coated exterior in blue, pink, or yellow provides scratch resistance and comfortable handling.
Complete Drinking System
Includes BPA-free lid with sliding closure, reusable stainless steel straw with silicone tip, and cleaning brush. Lid creates seal to prevent spills during transport.

Common Questions
Will this fit in my car cup holder?
The 3.5-inch diameter base fits standard vehicle cup holders. Measure your cup holder depth to confirm the 8.5-inch height clears your dashboard.
Can I put this in the dishwasher?
No. Dishwasher heat and detergents damage the vacuum seal and powder coating. Hand wash with warm soapy water and the included brush.
Does the straw work for hot drinks?
The straw is designed for cold beverages. For hot coffee or tea, remove the straw and drink directly from the lid opening to avoid burns.
How do I clean inside the straw?
Use the included thin brush to scrub inside the straw after each use. Rinse thoroughly and air dry before reassembling.
Will the color fade or chip?
The powder-coated finish resists normal wear, scratches, and fading. Avoid dropping on hard surfaces, which can chip the coating and expose bare steel.
