CS COSDDI CS20210107 12 oz Stainless Steel Travel Coffee Mug with Double-Wall Insulation

Take coffee or tea along on a commute, to the office, or around the house with a 12-ounce mug designed for everyday carry. Its double-wall vacuum insulation helps keep drinks hot or cold for up to 6 hours. A locking lid and compact format make it practical for travel and car cup holders.

Why it makes sense

The 12-ounce capacity suits a personal coffee or tea without the bulk of a larger travel tumbler. The stainless steel body has a matte black finish, while double-wall vacuum insulation helps maintain beverage temperature for up to 6 hours. That combination works for a morning drink on the way to work, a cup at a desk, or a beverage to take along while traveling.

The lid uses a silicone seal and a locking design intended to help prevent spills during everyday carrying. For buyers choosing between an open ceramic mug for stationary use and a travel tumbler for the commute, this mug brings insulation and a lid into a smaller, cup-holder-friendly format. Its reusable stainless steel construction also makes it suitable for regular use with hot drinks and other beverages.

Worth noting

The mug is made from 304 stainless steel and is described as BPA-free. Its double-wall construction is the key feature for keeping a drink warm or cold while moving between home, car, and work. The included lid opens and closes for drinking, and the wide mouth makes access easier when cleaning by hand.

Buyer feedback often highlights the size, appearance, temperature retention, and fit in car cup holders. Experiences with the lid and leak resistance are mixed: some buyers report a secure seal and spill-free carrying, while others say the lid did not close properly or the mug leaked. The lid’s locking design is intended for carrying, but buyers’ experiences vary. This feedback is useful context for anyone prioritizing a travel lid alongside a compact insulated cup.

Cleaning & care

Hand wash the mug. Its wide mouth provides access for hand cleaning, and the reusable stainless steel body is suited to regular drink service. Before carrying it with a hot drink, close and lock the lid securely. For travel, keep the mug upright when practical, particularly when carrying it in a bag.

When it makes sense

This is a useful format for someone who wants a personal-size insulated mug for coffee or tea at home, at the office, or on a commute. The 12-ounce capacity and stated fit for most car cup holders support day-to-day travel, while the vacuum-insulated walls help maintain drink temperature for up to 6 hours. Choose it when a compact stainless steel cup with a lid fits your routine better than a larger tumbler or an open mug kept at a desk.
