Nobody worries about a plastic bottle of cold water. Pour boiling tea into the same plastic and the question changes, because heat is what makes a material give something back.
What Are the Key Features of This BPA-Free 18/8 Steel Insulated Coffee Mug?
Declared BPA free where it counts - the lid, the seal and the sip opening are the plastic on any mug, and they are the parts against your mouth while the drink is near boiling.
18/8 food-grade steel chamber - non-porous, so this afternoon's tea does not arrive tasting of this morning's coffee, which is what happens in a lined or coated mug.
Powder-coated body, not polished - a matte coat stays in a hand that is holding something else, and it does not carry every fingerprint the way a mirrored finish does.
500 ml at 300 g empty - a mug you set down and come back to through a working morning, rather than a small cup you refill four times.
Three care rules - hand wash only, never microwave, never freeze; all three are worth following on a vacuum-walled body.
Where Can You Use This Insulated Coffee Mug?
A desk you sit at for hours
A workshop bench
A lecture hall, or a long study session
A bedside table on a cold night
Why Choose an 18/8 Steel Mug Over a Lined or Coated One?
18/8 steel gives flavour nothing to sit in - coffee, tea and soup go through the same mug, and a lined interior starts handing yesterday's drink back about a month in.
