Travel mug Contigo Streeterville 420 ml black - insulated spill‑proof tumbler

The Contigo Streeterville travel mug is a 420 ml insulated tumbler in black, designed to transport hot or cold beverages while minimizing spills. The compact cylindrical body fits most car cup holders and is intended for daily use at the office, during commuting, or on short trips. The mug combines vacuum insulation with a spill‑proof lid and one‑hand operation for convenient beverage access and temperature retention throughout the day.

Advantages

The double‑wall vacuum construction reduces heat transfer to keep hot drinks warm and cold drinks cool for extended periods without condensation on the exterior. The spill‑proof lid design helps prevent accidental leaks, and the single‑hand open/close mechanism enables quick drinking while on the move. The black finish is scratch‑resistant and easy to clean, and the size balances capacity with portability for everyday carry.

Suitable for

• Commuting and car travel where a secure cup holder fit is required
• Office use for maintaining drink temperature at a desk
• Short trips, walks, and public transport
• Everyday reusable alternative to disposable cups

How to use

Fill the mug with a hot or cold beverage up to the indicated level, secure the spill‑proof lid by aligning and locking it into place, and operate the one‑hand mechanism to drink or close.
