Cosori Coffee Mugs Set of 2 — 17 oz Stainless Steel Tumblers with Lids & Silicone Sleeves, Insulated & Spill-Resistant

Two 17 oz Cosori stainless steel coffee mugs with secure lids and silicone sleeves designed to keep your beverages insulated, stable, and spill-reduced for daily use.

These Cosori cups are a practical duet: 17-ounce, 304 food-grade stainless steel tumblers finished with slip-resistant silicone sleeves and snap-fit lids. They combine durable, BPA-free materials with a wide mouth for easy sipping and a lid opening sized for stirring. The set includes two color-differentiated mugs, dishwasher-safe components, and a flat bottom engineered to sit steadily on warming plates like Cosori’s coffee warmer.

How do these mugs keep drinks secure and easy to handle?

The slip-resistant silicone sleeve wraps the mug body to improve grip and reduce the risk of drops. The wide flat base provides full contact on flat surfaces and warming plates to prevent tipping. The lid snaps on to reduce spills during transport but is designed for easy thumb removal.

• Silicone sleeve for non-slip grip and heat protection
• Snap-fit lid with spoon-friendly opening
• Wide flat base for stability on countertops and warmers

What materials are used and are they safe for everyday drinking?

Cosori mugs are crafted from 304 food-grade stainless steel, which resists rust and discoloration while remaining lightweight. All plastic components are BPA-free to minimize exposure to unwanted chemicals. The materials are built for regular use and cleaning without leaching or tarnishing over time.

Can these mugs be used with warming devices and in daily routines?
