MEWAY 12oz Insulated Stainless Steel Coffee Mugs with Handle — White 4‑Pack, Double‑Wall Vacuum, Sliding Lids

MEWAY 12oz stainless steel mugs are insulated, handled travel tumblers sold as a set of four that keep drinks hot or cold for hours and include sliding lids for spill reduction.

These MEWAY 12oz mugs combine 18/8 food‑grade stainless steel construction with double‑wall vacuum insulation and a comfortable handle to make everyday drinking and travel easier. Designed for both hot coffee and chilled beverages, the set of four white powder‑coated tumblers offers a no‑sweat exterior, an interior polished to resist flavor transfer, and a sliding lid for controlled sipping. The mugs are lightweight enough for packing yet sturdy for repeated use during commutes, camping, or office breaks.

How long will a drink stay hot or cold in the MEWAY 12oz tumblers?

Thermal performance relies on ambient conditions and initial temperature, but the double‑wall vacuum design slows heat transfer so hot drinks stay warm and cold ones remain chilled significantly longer than single‑walled cups. Expect several hours of temperature retention suitable for most day‑to‑day needs.

• Keeps cold drinks icy for up to approximately 9 hours under normal conditions
• Maintains hot beverages warm for around 3+ hours in typical environments
• Vacuum barrier prevents exterior condensation and keeps hands dry

What makes these tumblers durable and safe for daily use?

The mugs use 18/8 stainless steel, a corrosion‑resistant alloy common in foodservice, and are free from BPA plastics touching the liquid. The powder-coated finish improves grip and resists scratches, while the electro‑polished interior minimizes odor and flavor carryover between uses.

• 18/8 food‑grade stainless steel body for rust resistance and longevity
• Electro‑polished interior prevents metallic tastes and simplifies rinsing
• Powder coating for an anti‑slip feel and improved scratch resistance

Are these tumblers convenient to clean and travel with?

MEWAY recommends hand washing to preserve the exterior finish and lid seals, but the smooth interior makes rinsing fast and effective. The 12oz size and attached handle make the mugs easy to hold, stow in backpacks, or place on picnic tables—ideal for on‑the‑go use.

• Hand wash recommended to protect the powder coat and lid components
• Compact 12oz capacity fits many cup holders and backpack pockets
