Vivulla68 Cool Grandma Club Tumbler 20oz - Double-Wall Insulated Stainless Steel with Lid & Straw

This stainless-steel tumbler pairs a cheerful "Cool Grandma Club" motif with durable vacuum insulation, making it a useful everyday cup and a thoughtful present for birthdays, Mother’s Day, or “just because.” It’s designed to preserve beverage temperature while resisting condensation and fits most cup holders for easy daily use. The included spill-resistant lid and reusable straw add convenience whether grandma is at home, in the car, or outside in the garden.

How long will my coffee or iced tea stay at the right temperature?

The double-wall vacuum construction slows heat transfer so hot drinks remain warm and chilled drinks stay cool for many hours under normal conditions. This delivers consistent sipping temperature without frequent reheating or early dilution of iced beverages.

• Hot beverages: stays warm for over 4 hours in standard indoor conditions
• Cold beverages: stays cold for more than 10 hours in typical use
• Vacuum-sealed stainless steel minimizes flavor change and prevents sweating

Is the tumbler practical for everyday use and travel?

Yes. The tumbler is shaped to fit most vehicle cup holders and comes with a secure lid and straw to reduce spills while on the move. Its lightweight but sturdy construction makes it easy to carry from the kitchen to the porch or into the car.

• Fits most standard cup holders for commuting or errands
• Secure snap-on lid and reusable straw for spill reduction

What makes this a good gift for grandmothers?

How do I care for the tumbler to keep it looking and performing its best?

Hand washing is recommended to protect the decoration and maintain insulation performance over time. Remove the lid and straw for thorough cleaning, and avoid abrasive cleaners that could dull the finish.

• Remove lid and straw to clean crevices and prevent buildup
• Avoid bleach, strong detergents, and the dishwasher to preserve the print
