Frequently Asked Questions
Are 40-oz. tumblers with handles dishwasher safe?
Yes! All our tumblers are top-rack dishwasher safe, including this 40-oz. size. The powder-coated exterior and stainless steel construction handle everyday cleaning without losing their finish.
Will a 40-oz. tumbler fit in my car's cup holder?
Surprisingly, yes. The tapered bottom fits into most standard cup holders, so you can take your tumbler on the road without juggling or wedging it between seats.
Can I customize a 40-oz. tumbler with a handle for my team or event?
Absolutely. You can add your logo, artwork, or message with precision laser etching. Just head over to our bulk custom drinkware page to get started.
What materials are WATR tumblers made from?
All our tumblers are made with premium 18/8 stainless steel and finished with a durable, powder-coated exterior. They're BPA-free, double-walled, vacuum-insulated, and built to last.
