What is the difference between CDI’s double wall, and double wall insulated stainless steel tumblers?
CDI’s double wall items have a stainless outer wall and an acrylic liner to comfortably transport hot beverages. CDI’s vacuum insulated stainless tumblers have both a stainless inner and outer wall from which the air between the walls has been removed to maintain the temperature of hot and cold beverages for hours.
Do CDI’s double wall tumblers “sweat”?
No. CDI’s blank double wall tumblers remain condensation free regardless of a liquid’s temperature.
Are CDI’s stainless-steel tumblers dishwasher safe?
Yes, though we recommend using the top rack of your dishwasher when washing.
