Rtteri 20 oz Insulated Tumblers 4-Pack — Colorful Employee Appreciation Set with Lids & Straws

These Rtteri 20 oz insulated tumblers come as a 4-piece set designed for employee appreciation and everyday use, featuring motivational prints, vacuum insulation, and travel-friendly lids and straws.

Give a practical, attractive token of thanks with this set of four Rtteri tumblers. Each 20 oz mug is crafted from durable 304 stainless steel with a scratch-resistant finish and a printed message to celebrate someone’s work and dedication. The tumblers include spill-resistant lids, reusable straws, and cleaning brushes so recipients receive a ready-to-use gift that’s suited for coffee, tea, water, or cold beverages while commuting, at the office, or at home.

How well do these tumblers keep drinks hot or cold?

Rtteri tumblers use double-walled vacuum insulation to slow temperature transfer and preserve your beverage’s ideal temperature for hours. They won’t perform like lab-grade flasks, but they reliably help hot drinks stay warm and cold drinks remain chilled throughout a typical workday.

• Warm beverages: maintains warmth for about 5 hours under normal use.
• Cold beverages: retains chill for roughly 9 hours when pre-chilled.
• Double-wall stainless steel prevents exterior condensation on cold drinks.
• Included lid and straw reduce heat/cold loss and make sipping on the go easier.

What materials and durability features does the set include?

These tumblers are manufactured from 304-grade stainless steel, chosen for corrosion resistance and repeated use. The exterior finish is scratch-resistant to keep them looking good in shared work environments, and the components are made to withstand daily handling.

• 304 stainless steel body — rust resistant and long-lasting.
• Scratch-resistant outer coating helps prevent visible wear.
• Resealable lids and reusable straws reduce disposable waste.
• Each set includes cleaning brushes to maintain hygiene and lifespan.
